     FIELD OF THE INVENTION 
     The present invention relates to a technology for testing internationalized software executed in a plurality of language environments. More particularly, the present invention relates to a technology concerning a test of an output to a user from the internationalized software executed in a language environment different from that of an original language, which is capable of improving visibility of test objects to enable efficient testing. 
     BACKGROUND OF THE INVENTION 
     Software supporting a plurality of languages is called “internationalized software”. In the internationalized software, a text string part to be displayed on a screen is separated from the source code, and the text string part thus separated is stored as an externalized resource file. The externalized resource file is referred to upon execution of the internationalized software, and used by the internationalized software to make a screen display. When such a configuration is employed, it is only necessary for a developer of the internationalized software to translate the externalized resource file to another language to make the internationalized software support the other language. Moreover, once the externalized resource file is translated, it is unnecessary to redo the translation even if the execution code is changed. 
     In a development process of such internationalized software, tests are conducted for various characteristics or aspects (hereinafter, referred to as “test categories”) to see whether the internationalized software operates properly in language environments of different countries. Among them, the tests concerning an output to the user include one that checks whether a message or other character string to be displayed to the user has been separated from the source code and externalized properly as a resource file. In other words, this is a hard-coded character string detection test that confirms that the message or other character string to be displayed to the user is not directly described (i.e., hard-coded) in the source code. There also is a validation test of a sort result that checks whether a list of character strings is sorted properly in the order defined in each language, such as alphabetic order. Also conducted is a displayability test of language-specific characters that checks whether characters specific to each language are displayed properly without being garbled, for example. 
     Translation of the externalized resource file takes time. Thus, in the development process, it is not feasible to use a translated, externalized resource file for testing each problem category described above in each desired language. For this reason, there was conventionally developed a method for mock-translating an externalized resource file to use it as the externalized resource file that approximates certain attributes, such as character length, of a target language. In this conventional technology, the mock translation includes placeholder data, e.g., characters, that expands the spacing allocated to the text to accommodate for the spacing required for translations. In a preferred embodiment, all English text that would appear on the graphical user interface (i.e., buttons, menus, pop-up dialogs, dialog window titles, dialog text, error messages, help windows, etc.) is expanded using tildes, and is enclosed with brackets, i.e., [ ]. This mock translation data is stored in localization files and displayed in a software application in place of the English or foreign-language text. The GUI is then tested by visually inspecting each screen. The programmer or proofreader is able to easily recognize many errors that would occur if the GUI were to be displayed in a translated language, without requiring the ability to read any foreign languages. These errors, referred to as internationalization errors, include truncation, expansion, alignment, or other formatting errors, and programming errors such as text that is hard-coded, text missing from localization files, localization files missing from the program build, and text composed of more than one translated message (see U.S. Pat. No. 6,507,812 and U.S. Pat. No. 6,453,462). There also is a technology in which narrow or single-width alphabetic characters of the original language are all replaced with wide or double-width alphabetic characters to create a mock translation (see U.S. Pat. No. 6,425,123). In these technologies, it is confirmed that on a screen display of the output of the internationalized software that performs processing by referring to the mock-translated resource file, the added characters or the double-width alphabetic characters are displayed properly for each of the character strings of the original language. If only a character string of the original language is displayed, it is a hard-coded character string. Further, if any of the added characters or the double-width alphabetic characters is replaced with another character, it is a garbled character. 
     SUMMARY OF THE INVENTION 
     The invention improves techniques for internationalizing software by using mock translation files. A second file of messages to be outputted by the software is created from a first file of messages. The messages in the first file are written in a first language. The creating of the second file comprises for each message in the first file, 
     a) applying specified rules to form a second message by changing the character length of the second message, 
     b) filling in any blank characters in the second message with a dummy character, 
     c) inserting characters from the target language into prescribed places in the second message to form a second message having both characters of the first language and characters of the target language, and 
     d) copying the second message into the second file, 
     and executing the software using the second file. 
     In another embodiment, a second file of messages to be outputted by the software is created from the first file of messages. The messages in the first file are written in a first language. One or more test characters in a target language are selected. The creating of the second file comprises for each message in the first file, translating all characters in the first language corresponding to the test characters to the corresponding characters in the target language, and changing all other characters in the message to a dummy visible character, copying the translated message into the second file and executing the software using the second file. 
     In view of the foregoing, the invention improves the mock translation of the conventional art. The first improvement is that, for each string item in the resource file of the original language, different characters of the translation target language that would likely cause a problem are added before and after, or only before, the first characters of the character strings of the original language in the mock resource file. The second improvement is that marks indicating the beginning and the end of an assignment portion of a string item are added before and after the assignment portion in the mock resource file. With these improvements, on the screen display of the output of the internationalized software performing processing by referring to the mock-translated resource file, different characters of the translation target language are displayed in front of the character strings of the original language. Accordingly, it has become possible to conduct the validation test of the sort result on the display screen of the internationalized software using the improved mock translation, which was not possible with the above-described conventional technologies. Furthermore, with the improved mock translation, different characters of the translation target language of an arbitrary length can be added to different first characters of the character strings of the original language. Thus, in the improved mock translation, it has become possible to conduct the displayability test for a greater number of language-specific characters using a single resource file. Still further, on the screen display of the internationalized software using the improved mock translation, the marks indicating the beginning and the end of the assignment portion are displayed before and after the assignment portion. As a result, the assignment portion has become distinguishable, and accordingly, in the improved mock translation, it has become possible to appropriately conduct the detection of the hard-coded character string(s) for the assignment portion. 
     The improved testing method described above, however, still has several problems. Firstly, in the improved testing method of the conventional art, although the assignment portion may be identified, there still is a possibility that a hard-coded character string may be overlooked. Further, in the improved testing method, although it may be possible to confirm that the list of the character strings is sorted as a result of sorting, a tester who does not have any knowledge about the translation target language cannot determine whether the sort result is correct or not. Even a tester having knowledge about the translation target language will not be able to immediately determine whether the sort result is correct or not for Japanese or other language having a great number of types of characters. Furthermore, with the improved method, an increased number of types of characters of the translation target language are displayed on the screen, making it impossible for the tester to immediately determine whether there is any garbled character among the characters displayed on the screen. 
     Moreover, in the improved testing method, it is tried to check for all the test categories on a single display screen of the internationalized software that performs processing by referring to the mock-translated resource file; this results in poor visibility of the test objects. If different externalized resource files suitable for the respective contents of the test categories are prepared, however, it will be necessary to restart the internationalized software the number of times corresponding to the number of test categories, which hinders efficient testing. 
     In view of the foregoing, an object of the present invention is to provide a method, apparatus and program for efficiently testing internationalized software with improved visibility of the test objects and with no need of restarting the internationalized software, and to provide a data structure of a font used for the test. Another object of the present invention is to ensure that hard-coded character strings are detected without omission in the test of the internationalized software. A further object of the present invention is to ensure that, when a plurality of character strings are sorted, determination as to whether the sort result is proper can be made irrespective of presence/absence of knowledge about the translation target language in the test of the internationalized software. Yet another object of the present invention is to facilitate determination as to whether there is any garbled character in the test of the internationalized software. 
     To achieve the above-described objects, the present invention provides a method for testing internationalized software executed by a computer as follows. Herein, the internationalized software refers to software that performs processing by referring to an externalized resource file and that is executed in a plurality of language environments. The method for testing the internationalized software includes the steps of: reading data from the externalized resource file written in a first language; generating a test resource file written in a second language from the externalized resource file written in the first language by converting characters of the first language included in the data to characters of the second language by referring to a conversion table having the characters of the first language and the characters of the second language associated one for one with each other; executing the internationalized software; and displaying output information outputted from the internationalized software that performs processing by referring to the test resource file as the externalized resource file on a screen by using one of a plurality of fonts prepared for respective test categories of the internationalized software. 
     Herein, character codes included in the output information can be classified into three groups: a first group of a plurality of character codes corresponding to the characters of the first language, which are not supposed to be included in the output information; a second group of a plurality of character codes corresponding to the characters of the second language included in the conversion table, which are supposed to be included in the output information; and a third group of a plurality of character codes not corresponding to either the characters of the first language or the characters of the second language included in the conversion table, which are not supposed to be included in the output information. Further, each of the plurality of fonts employing a prescribed coding scheme uses different association rules when associating character shapes to a group of a plurality of character codes that are test objects in a test of the internationalized software and a group of the other character codes in the prescribed character coding scheme, such that the character codes as the test objects and the other character codes are distinguishable from each other in a display of the output information using the relevant font. 
     Therefore, according to the present invention, the character codes as the test objects are displayed in a manner distinguishable from the other character codes, which improves visibility of the test objects. While the test objects differ for each test category, according to the present invention, a plurality of fonts are prepared for the respective test categories, so that it is possible to provide a display screen suitable for the test for each test category by only using the corresponding font, without the need to restart the internationalized software. 
     Preferably, the step of displaying the output information using one of the plurality of fonts includes the step of displaying the output information using one font selected by a user from the plurality of fonts. Alternatively, the above step includes the step of displaying the output information by switching the font being used to one font selected by a user from the plurality of fonts. Further, preferably, the conversion table has some of the characters of the first language associated one for one with some of the characters of the second language that would likely cause a problem in terms of display. 
     Further, preferably, the test categories include detection of a hard-coded character string. In the font used for the detection of the hard-coded character string, the first group corresponds to the group of a plurality of character codes that are the test objects, and the character codes of the first group are each associated with the character shape of the character of the first language corresponding to the relevant character code without modification. Preferably, the above font causes each of the other character codes in the prescribed character coding scheme to be associated with a same character shape. The same character shape is preferably a less frequently used symbol or an inconspicuous symbol such as a hollow square symbol. 
     Further, preferably, the test categories include validity of a sort result of character strings according to the order of characters defined in the second language. In the font used for the determination of validity of the sort result, the second group corresponds to the group of a plurality of character codes that are the test objects, and the character codes of the second group are each associated with the character shape indicating the order defined for the character of the second language corresponding to the relevant character code. Preferably, the above font causes each of the other character codes in the prescribed character coding scheme to be associated with a same character shape. The same character shape is preferably a less frequently used symbol or an inconspicuous symbol such as a hollow square symbol. 
     Further, preferably, the test categories include displayability of characters specific to the second language. In the font used for the determination of displayability, the third group corresponds to the group of a plurality of character codes that are the test objects, and the character codes of the third group are each associated with a same character shape. The same character shape is preferably a less frequently used symbol or a conspicuous symbol. 
     Further, preferably, the test categories include character string confirmation for confirming the character strings included in the externalized resource file written in the first language. In the font used for the character string confirmation, the second group corresponds to the group of a plurality of character codes that are the test objects, and the character codes of the second group are each associated with the character shape of the character of the first language that has the character of the second language corresponding to the relevant character code as a converted-to character upon generation of the test resource file. In the above test category, the first group also corresponds to the group of a plurality of character codes that are the test objects, and the character codes of the first group are each associated with the character shape of the character of the first language corresponding to the relevant character code without modification. 
     According to another aspect of the present invention, there is provided a data structure of a font employing a prescribed character coding scheme used in a test of internationalized software that refers to a test resource file generated by converting all the characters of a first character included in an externalized resource file written in the first language to characters of a second language one for one based on a conversion table. The data structure includes: a plurality of first character codes that are test objects in the test; a plurality of items of first character shape information associated one for one with the plurality of first character codes according to a first rule; a plurality of second character codes that are other character codes in the prescribed character coding scheme; and a plurality of items of second character shape information associated one for one with the plurality of second character codes according to a second rule. 
     Here, the plurality of first character codes correspond to one of a plurality of character codes corresponding to the characters of the first language, a plurality of character codes corresponding to the characters of the second language included in the conversion table, and a plurality of character codes not corresponding to either the characters of the first language or the characters of the second language included in the conversion table. When the first character code is detected from an output of the internationalized software that performs processing by referring to the test resource file, the first character shape information corresponding to the relevant first character code is retrieved from the font data and used for screen display. When the second character code is detected from the output, the second character shape information corresponding to the relevant second character code is retrieved from the font data, which is used for screen display. 
     While the present invention has been explained above as the method for testing the internationalized software, it is also possible to understand the present invention as an apparatus, a program, or a storage medium storing the program. Further, the features explained in conjunction with the method for testing the internationalized software may be adapted to the data structure of the font used for the test of the internationalized software explained as another aspect of the present invention. Furthermore, the present invention explained as the data structure of the font may also be understood as a recording medium storing the relevant data structure of the font. 
     According to the present invention, it is possible to conduct an efficient test concerning an output to a user of internationalized software executed in a language environment different from that of an original language, with improved visibility of the test objects and with no need to restart the internationalized software for each test category. Other advantages will be explained in the following description of the embodiments of the present invention.

     DETAILED DESCRIPTION OF THE INVENTION 
     As will be appreciated by one skilled in the art, the present invention may be embodied as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product on a computer-usable storage medium having computer-usable program code embodied in the medium. 
     Any suitable computer usable or computer readable medium may be utilized. The computer-usable or computer-readable medium may be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium.

Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-usable medium may include a propagated data signal with the computer-usable program code embodied therewith, either in baseband or as part of a carrier wave. The computer usable program code may be transmitted using any appropriate medium, including but not limited to the Internet, wireline, optical fiber cable, RF, etc. 
     Computer program code for carrying out operations of the present invention may be written in an object oriented programming language such as Java®, Smalltalk, C++ or the like. However, the computer program code for carrying out operations of the present invention may also be written in conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). 
     The present invention is described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions. 
     The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     The corresponding structures, materials, acts, and equivalents of all means or step plus function elements in the claims below are intended to include any structure, material, or act for performing the function in combination with other claimed elements as specifically claimed. The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the invention. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated. 
     Prior to the description of the present invention, an externalized resource file of internationalized software, an improved mock translation method and problems thereof will be explained with reference to  FIGS. 1A ,  1 B,  1 C,  2 A, and  2 B. Hereinafter, the internationalized software is referred to as a “program to be tested” or “test object program”, and the externalized resource file is simply referred to as a “resource file”.  FIG. 1A  shows, as an example of the resource file, a resource file  100  of a test object program with English as the original language. As shown in the figures, the resource file includes a plurality of items, each consisting of a key and a character string to be assigned to the key. When the test object program encounters a key at the time of execution, it searches the resource file for the relevant key, and reads the value of the character string to be assigned to the key. This operation will now be described in more detail using a source code  105  shown in  FIG. 1B  and an output screen  110  of the test object program shown in  FIG. 1C . 
     The command “showMessage( )” included in the source code  105  is a command to display on a screen a character string obtained by assigning the second argument to the variable included in the character string of the first argument. Specifically, when executing the “showMessage” command, the test object program retrieves the key “MSG01” as the first argument from the resource file  100 , and reads the corresponding character string value “The status is {0}.” The test object program then assigns “Green”, received as the second argument, to {0} of the read character string value, to eventually display “The status is Green.” on the screen, as shown in  115  in  FIG. 1C . It is noted that {0} included in the character string assigned to the key MSG01 is an “assignment portion”, and the variable assigned to {0} has its value determined at the time of execution. 
     Now, the improved mock translation method and problems thereof will be explained with reference to  FIGS. 2A and 2B . As described above, in the improved mock translation, different characters of a translation target language that would likely cause a problem are added before and after the first character of the character string of the original language for each item in the resource file of the original language. Further, marks indicating the “beginning” and the “end” are added before and after the assignment portion included in the resource file. The mock-translated resource file  200  shown in  FIG. 2A  corresponds to the resource file  100  shown in  FIG. 1A  that is mock-translated according to the improved technology. Herein, the translation target language is Japanese. 
     As seen from  FIG. 2A , in this example, the characters
     “         ”
 
and
   “         ”
 
and the characters
   “         ”
 
and
   “         ”
 
are selected and added before and after the first characters of alphabets “T” and “G”, respectively, as the characters that would likely cause a problem. For the first characters of the other items, different Japanese characters are selected and added before and after the different alphabets. The first character of each item is put in “( )”, facilitating identification of the first character. Further, the characters
   “         ”
 
and
   “         ”
 
are added before and after the assignment portion {0}.
   

       FIG. 2B  shows a screen  205  that is displayed when the test object program, read for execution of the mock translation, executes the source code shown in  FIG. 1B . Focusing on the character string “Green” displayed in the field  210 , the characters
     “         ”
 
and
   “         ”
 
are displayed before and after “Green”, with no Japanese characters added before and after the first character “G”, and it is thus understood that this character string is a hard-coded, assigned character string. The first characters of the three character strings in the list box  215  each have different Japanese characters added before and after the same, and it is thus understood that it is possible to carry out a validation test of a sort result by executing the Sort command. Furthermore, the Japanese characters displayed before and after the first character “R” of the character string “Refresh the Status” displayed on the button  225  are different from the initially added Japanese characters, so that it is understood that there is a problem in display of the characters
   “         ”
 
and
   “         ”
 
in the relevant portion.
   

     However, the testing method utilizing such improved mock translation still has several problems as described above. One problem is that, although the assignment portion may be identified, the hard-coded character string may be overlooked. As for the character string having an assignment portion, not only the original character string having a character string assigned thereto, but also the character string in the assignment portion have to be confirmed whether it is a hard-coded character string or not. The confirmation of the hard-coded character string is carried out based on the first character of the character string as described above. This means that, when the assignment portion is in the middle of the character string, as is the case of the character string in the field  210  of  FIG. 2B , the confirmation of the hard-coded character string may not be possible for the assignment portion that is not positioned at the beginning of the character string. 
     Another problem is that, even if it can be confirmed that the list of the character strings is rearranged as a result of sorting, determination as to whether the sorting is proper is difficult. It will be difficult for not only the tester who does not have any knowledge of the translation target language but also the tester who has knowledge thereof to immediately determine whether the sorting has been correctly performed or not for a language having a great number of characters like Japanese. Yet another problem is that in the testing method utilizing the improved mock translation, a large number of types of characters of the translation target language are displayed on the screen, hindering immediate determination as to whether there is any garbled character in the displayed characters. For example, it is not possible to identify the garbled characters by seeing the display screen  205  in  FIG. 2B  alone. 
     Furthermore, with the improved testing method, visibility of the test objects on the display screen is low, since a single display screen of the internationalized software that performs processing by referring to a mock-translated, externalized resource file is used to try to confirm the results all at once. On the other hand, if an externalized resource file suitable for the test content is to be prepared for every test category, it will be necessary to restart the internationalized software the number of times corresponding to the number of test categories, hindering efficient testing. 
     In view of the foregoing, the present invention solves the above-described problems by using a newly developed test resource file and a plurality of fonts prepared for the respective test categories. More specifically, the present invention makes it possible to provide a display screen suitable for the test for each test category, while preparing only one mock-translated resource file for the test, by displaying the output from the test object program that performs processing by referring to the resource file by using a plurality of fonts prepared for the respective test categories. The problems specific to the respective test categories are solved by preparing a plurality of fonts for the respective test categories, and by making the character codes as the test objects distinguishable from the character codes that are not the test objects, while giving some thought to the character shapes to be associated with the character codes. 
     Firstly, a novel method of mock translating a resource file according to the present invention will be described with reference to  FIGS. 3 ,  4 A,  4 B,  4 C,  5 A, and  5 B. Subsequently, a method of testing a test object program using the mock-translated resource file and a plurality of fonts prepared for the respective test categories will be described with reference to  FIGS. 3 ,  7 A,  7 B,  8 A,  8 B,  9 A,  9 B,  10 A,  10 B,  11 A, and  11 B. 
     The portion in  FIG. 3  delimited by a dotted line is a functional block diagram of an apparatus  300  for creating a test resource file according to an embodiment of the present invention. The apparatus  300  includes: a first storage unit storing an original resource file  310  and a conversion table  320 ; test resource file generating unit  330 ; and a second storage unit storing a test resource file  340 . It is noted that the first and second storage units may physically be a single storage device. Further, while Unicode is employed as a prescribed character coding scheme in the present embodiment, the present invention is not restricted thereto, and it is of course possible to employ any other character coding scheme. The “character code” as used herein is a code associated with a character, which is called a “code point” in Unicode. 
     The original resource file  310  is an original resource file referred to by the test object program during execution.  FIG. 4A  shows, as an example of the original resource file  310 , a resource file  400  in which the original language is English. In the present embodiment, the translation target language is Japanese. The conversion table  320  is a table in which the characters of the original language as the first language and the characters of the translation target language as the second language are associated with each other one for one. In order to enable such one-to-one mapping, it is required that the range of the character codes of the characters used in the translation target language is greater than the range of the character codes of the characters used in the original language. For example, English (ASCII code) uses the smallest range of the character codes, so that it is possible to select Japanese, Chinese, Korean or French as the translation target language. In contrast, when French is the original language, although it may be possible to select Japanese or Chinese as the translation target language, it is not possible to select English. Preferably, in the conversion table  320 , some of the characters of the original language are associated one for one with the characters of the translation target language that would likely cause a problem in terms of display. 
     Here, the characters that would likely cause a problem in terms of display will be described with reference to Japanese characters by way of example. Firstly, the Japanese characters
     “         ”   “         ”
 
and
   “         ”
 
each have the character code in which the second byte corresponds to the bit pattern used in the English language environment as a control code for line feed or the like, so that it may not be displayed properly in some type of the character coding scheme being used. Further, several Japanese characters including
   “         ”
 
may be converted to different characters in some type of the character coding scheme being used. For example, while the character code of
   “         ”
 
is U+9BF5 in Unicode, this is converted to 0X88B1 in the character coding scheme called “MS932”, whereas it is converted to 0XE9CB in the character coding scheme called “CCSID 942”. Even the characters other than those that are known to possibly cause a problem may not be displayed properly. Accordingly, it is desirable in the conversion table  320  that some of the characters of the original language are associated one for one with the characters of the translation target language that would likely cause a problem, such that the table includes both the normal characters and the characters that would likely cause a problem in terms of display.
   

       FIG. 4B  shows, as an example of the conversion table  320 , a conversion table  405  in which English characters are associated one for one with Japanese characters. In the conversion table  405 , in the two columns on the left are the English characters and the character codes assigned thereto, and in the two columns on the right are the corresponding Japanese characters and the character codes assigned thereto. The conversion table  320  defines the correspondence for the characters used in the original language, except the meta characters that are symbols used when creating a pattern with regular expression. As seen from the conversion table  405 , in Unicode, the English characters except the meta characters are assigned with the character codes in the range from U+0020 to U+007E. Here, the English capital letters “S”, “T” and “U” are associated with
     “         ”   “         ”
 
and
   “         ”
 
respectively, that would likely cause a problem.
   

     The test resource file generating unit  330  reads the original resource file  310  and the conversion table  320  from the first storage unit, and converts the characters of the first language to the characters of the second language based on the conversion table  320 , to thereby generate a test resource file  340  written in the second language from the resource file  310  of the test object program written in the first language. The test resource file  340  thus generated is stored in the second storage unit as the resource file of the test object program.  FIG. 4C  shows a test resource file  410  that is generated from the original resource file  400  by converting the English characters to the Japanese characters based on the conversion table  405 . As seen from the figure, the test resource file  410  does not include any character of the original language of English. 
     An example of the process flow of the apparatus  300  according to the present embodiment will now be described with reference to the flowchart shown in  FIGS. 5A and 5B .  FIG. 5A  is a flowchart illustrating an outline of the process flow of the apparatus  300  of the present embodiment. The apparatus  300  firstly reads an original resource file  310  from the first storage unit (step  500 ). The apparatus  300  then converts the characters of the first language to the characters of the second language based on the conversion table  320 , to generate a test resource file  340  written in the second language from the original resource file  310  written in the first language of the test object program (step  505 ). Lastly, the apparatus  300  stores the generated test resource file  340  to the second storage unit (step  510 ). 
     Now, the process in the step  505  will be described in detail with reference to  FIG. 5B . Firstly, as pre-processing, the apparatus  300  reads the conversion table  320  from the first storage unit and an empty test resource file  340  from the second storage unit. Thereafter, the main process is started, and the test resource file generating unit  330  determines whether the original resource file  310  includes any readable item (step  515 ). If there is no readable item (step  515 : NO), the process is terminated. If it determines that there is a readable item (step  515 : YES), the test resource file generating unit  330  reads one item from the original resource file  310  (step  520 ). The test resource file generating unit  330  extracts a key from the read item and assigns it to a variable Key (step  525 ), and writes the variable Key to the test resource file  340  (step  530 ). 
     Next, The test resource file generating unit  330  extracts a character string value from the read item, and assigns it to a variable Text (step  535 ), and further reads one character from the variable Text and assigns it to a variable X (step  540 ). For confirmation of the assignment portion, The test resource file generating unit  330  confirms the value of the variable X, and if it is a numerical character, it confirms whether the values before and after the variable X correspond to “{” and “}”, respectively (step  545 ). If the value of the variable X is not a numerical character indicating the assignment portion (step  545 : NO), The test resource file generating unit  330  refers to the conversion table  320  to convert the character of the variable X, and assigns the converted character to a variable Y (step  550 ). If the value of the variable X is a numerical character indicating the assignment portion (step  545 : YES), The test resource file generating unit  330  assigns the value of the variable X as it is to the variable Y (step  555 ). It is assumed that the conversion table  320  defines such that the characters “{” and “}” become the same characters after the conversion. Thereafter, The test resource file generating unit  330  writes the variable Y to the test resource file  340  (step  560 ). It then confirms whether the character previously read from the variable Text is the last character (step  565 ). If it is not the last character (step  565 : NO), the process returns to the step  540 . If it is the last character (step  565 : YES), the process returns to the step  515 . 
     Returning to  FIG. 3 , the portion in  FIG. 3  delimited by a dashed-dotted line shows a functional block diagram of an apparatus  350  for testing a test object program using a mock-translated resource file and a plurality of fonts prepared for respective test categories, according to an embodiment of the present invention. Herein, the apparatus  300  for creating the test resource file and the apparatus  350  for testing the test object program are explained separately for convenience of the explanation. In effect, it is possible to implement the function of the apparatus  350  and the function of the apparatus  300  with a single computer. The apparatus  350  includes: the second storage unit storing the test resource file  340 , a test object program execution unit  355 , a display screen creation unit  360 , a font selection unit  365 , and a third storage unit including a plurality of fonts prepared for the respective test categories. The plurality of fonts included in the third storage unit include: a default font  370 , a hard-coded character detection font  375 , a garbled character detection font  380 , a reverse font  385 , a sort font  390 , and another font  395 . It is noted that the second storage unit and the third storage unit may physically be a same storage device. 
     The test resource file  340  stored in the second storage unit is a resource file written in a translation target language that is the second language, as explained above. The test resource file  340  is stored in the second storage unit as a resource file of the test object program. The test object program execution unit  355  executes the test object program. Upon execution of the test object program, the test object program execution unit  355  firstly reads the test resource file  340  from the second storage unit and, thereafter, refers to the test resource file  340  to execute processing of the test object program and outputs the processed results. 
     The display screen creation unit  360  receives the processed results from the test object program, and creates a display screen of the processed results using the default font included in the third storage unit. At this time, the display screen creation unit  360  temporarily stores the processed results received from the test object program in a buffer. The created display screen is transmitted to a display device for display. When receiving a designation of a font from the font selection unit  365 , the display screen creation unit  360  reads the processed results of the test object program from the buffer, and newly creates a display screen of the processed results using the designated font. The created display screen is again transmitted to the display device for display. 
     The font selection unit  365 , when receiving a selection request of a font to be used from a user via an input device such as a mouse, keyboard and the like, refers to the third storage unit to confirm available fonts, and creates a dialog box for font selection. The font selection unit  365  transmits the created dialog box to the display device. When receiving a designation of the font to be used from the user, the font selection unit  365  notifies the display screen creation unit  360  of the designated font type. 
     Now, prior to the description of the plurality of fonts prepared for the respective test categories according to the embodiment of the present invention, the processed results of the test object program displayed using a normal or regular font will be described. When the processed results of the test object program that performs processing by referring to the test resource file  410  shown in  FIG. 4C  are displayed using a regular font, a display screen  660  as shown in  FIG. 6  is obtained. It is noted that the display screen  110  shown in  FIG. 1C  is the display screen of the processed results of the test object program that performs processing by referring to the original resource file  100 . As described above, the test resource file  410  does not include any English characters, and thus, it is supposed that no English characters would be displayed on the output display screen. Accordingly, the English character string “Green” displayed in the field  665  in  FIG. 6  is a hard-coded character string. In the display screen  660 , however, there exist both Japanese characters and English characters, making it hard for the tester to immediately detect the hard-coded character string. 
     Further, the character string displayed on the button  680  in  FIG. 6  differs from the character string of MSG02 in the test resource file  410 , which means that it has garbled characters. However, since there are many types of characters displayed on the display screen  660 , it is not possible for the tester to determine that the character string displayed on the button  680  includes garbled characters by seeing the display screen  660  alone. Furthermore, the three character strings displayed on the list box  670  in  FIG. 6  include various Japanese characters such as hiragana letters, Chinese letters, katakana letters, and symbols, and accordingly, when the tester executes sorting, it is not possible for the tester to immediately determine whether the sort result is correct or not. As described above, when the test resource file according to the embodiment of the present invention is used together with a regular font, it is not possible to provide a screen display suitable for a test for each test category. 
     Hereinafter, the plurality of fonts prepared for the respective test categories according to the embodiment of the present invention will be explained. Firstly, the hard-coded character detection font  375  used for detection of hard-coded character strings will be explained. In the detection of the hard-coded character strings, a plurality of character codes corresponding to the characters of the original language as the first language correspond to a plurality of character codes as the test objects, or, the objects of detection. Since the test resource file  340  according to the present invention is created by converting all the characters of the original language included in the original resource file  310  to the characters of the translation target language based on the conversion table  320 , it can be said that any character of the original language included in the output of the test object program that performs processing by referring to the test resource file  340  should be the character hard-coded in the source code, or one derived from another resource that is not a test object. The character codes corresponding to the characters of the translation target language as the second language included in the conversion table  320 , and the character codes not corresponding to either the characters of the original language or the characters of the translation target language included in the conversion table  320 , correspond to a plurality of character codes that are not the test objects. 
     In the hard-coded character detection font  375 , all the character codes that are not the test objects are associated with a same character shape in order to improve visibility of the characters of the original language as the test objects on a screen. The same character shape is preferably an inconspicuous character shape such as a hollow square or a blank, a less frequently used character shape, or an inconspicuous and less frequently used character shape. On the other hand, the character codes of the original language as the test objects are associated with the character shapes of the characters of the original language corresponding to the relevant character codes without modification. 
       FIG. 7A  shows, as an example of the hard-coded character detection font  375 , a table  700  of the hard-coded character detection font in the case of creating a test resource file using the conversion table  405  shown in  FIG. 4B  with English as the original language and Japanese as the translation target language. In the leftmost column of the table  700  are the character codes, and in the rightmost column are glyphs in the hard-coded character detection font assigned to the corresponding character codes. It is noted that the “glyph” refers to a character shape assigned to a character code. Glyphs of a regular font are added in the central column of the table  700  for reference. In the table  700 , the character codes U+3000 to U+FFEA correspond to the Japanese characters included in the conversion table  405 . Since they are the character codes that are not the test objects as explained above, here, they are each assigned with a hollow square character shape. In the table  700 , the character codes U+0020 to U+007E correspond to the English characters. They are the character codes as the test objects as explained above, and thus, they are each assigned with the character shape of the original character. 
     The other character codes in the table  700  correspond to a plurality of other character codes of Unicode. Since they are not the test objects as explained above, they are each assigned with a hollow square character shape, as are the above-described character codes. It should be noted that the number of rows in the table  700  does not indicate the actual number of the character codes.  FIG. 7B  shows a display screen  705  in the case where the processed results of the test object program that performs processing by referring to the test resource file  410  shown in  FIG. 4C  are displayed using the table  700  of the hard-coded character detection font. In  FIG. 7B , the characters other than the hard-coded character string “Green” shown in the field  710  are all displayed as the hollow square symbols. As such, when the hard-coded character detection font  375  is used, the characters that are not the test objects are all displayed in the same character shape, which allows the tester to readily detect the hard-coded characters without being misled by the characters that are not the objects of detection including those of the translation target language. 
     The garbled character detection font  380  will now be explained that is used for determination of displayability of the characters specific to the translation target language as the second language. In the determination of displayability, the character codes not corresponding to either the characters of the original language or the characters of the translation target language included in the conversion table  320  correspond to a plurality of character codes as the test objects, or, the objects of detection. Since the test resource file  340  of the present invention is created by converting all the characters of the original language included in the original resource file  310  to the characters of the translation target language based on the conversion table  320 , the characters to be included in the output of the test object program that has read the test resource file  340  should be the characters of the translation target language included in the conversion table  320 . Nevertheless, the output may include the characters of the original language hard-coded in the source code or derived from another resource other than the test object, as described above in conjunction with the hard-coded character detection font  375 . The relevant characters of the original language are not those displayed as a result of garbling. Therefore, if the output includes any character other than the characters of the translation target language included in the conversion table  320  and the characters of the original language, it must be a character that is not supposed to be displayed, i.e., a garbled character. 
     As such, the character codes corresponding to the characters of the original language and the character codes corresponding to the characters of the translation target language included in the conversion table correspond to a plurality of character codes that are not the test objects. In the garbled character detection font  380 , the character codes as the test objects are all associated with a same character shape in order to improve visibility of the garbled characters as the test objects on the screen. The same character shape is preferably a conspicuous character shape such as a postal mark, or a character shape less frequently used and conspicuous. On the other hand, the character codes that are not the test objects are each associated with a same character shape that is different from the character shape associated to the character codes as the test objects. This same character shape is preferably an inconspicuous character shape such as a hollow square or a blank. 
       FIG. 8A  shows, as an example of the garbled character detection font  380 , a table  800  of the garbled character detection font in the case of generating a test resource file based on the conversion table  405  shown in  FIG. 4B , with English as the original language and Japanese as the translation target language. In the leftmost column of the table  800  are the character codes of the garbled character detection font  380 , and in the rightmost column are glyphs assigned to the corresponding character codes. Further, in the central column are glyphs in a regular font added for reference. In the table  800 , the character codes U+3000 to U+FFEA are those corresponding to the Japanese characters included in the conversion table  405 . As explained above, they are the character codes that are not the test objects, and thus, a hollow square character shape is assigned to each of them. 
     In the table  800 , the character codes U+0020 to U+007E are those corresponding to the English characters. They also are the character codes that are not the test objects as described above, and thus, a hollow square character shape is assigned to each of them. The other character codes in the table  800  are a plurality of other character codes in Unicode. Since they are the character codes as the test objects as explained above, the character shape of postal mark is assigned to each of them in this example. It should be noted that the number of rows in the table  800  does not indicate the actual number of character codes. 
       FIG. 8B  shows a display screen  810  in the case where the processed results of the test object program that performs processing by referring to the test resource file  410  shown in  FIG. 4C  are displayed using the table  800  of the garbled character detection font  380 . In  FIG. 8B , the postal marks are displayed on the button  830 , making it possible to immediately understand that garbled characters are displayed thereon. As such, when using the garbled character detection font  380 , the garbled characters are displayed in a prescribed character shape, thereby allowing the tester to readily detect the garbled characters even if the translation target language has a great number of types of characters. Moreover, the characters that are not the test objects, such as those displayed in the list box  820 , are displayed in the same, inconspicuous character shape, so that the tester can readily detect the garbled characters, without being misled by the characters other than the objects of detection, such as the characters of the translation target language, which are displayed correctly. 
     The reverse font  385  will now be explained that is used for confirmation of the character strings included in the resource file written in the first language. In the confirmation of the original character strings, the character codes corresponding to the characters of the original language and the character codes corresponding to the characters of the translation target language included in the conversion table  320  correspond to a plurality of character codes as the test objects, or, the objects of confirmation. Since the test resource file  340  of the present invention is created by converting all the characters of the original language included in the original resource file  310  to the characters of the translation target language based on the conversion table  320 , it is not possible to obtain information regarding the original character strings from the output screen of the test object program that performs processing by referring to the test resource file  340 . Thus, in order to obtain the information regarding the original character strings, the character codes corresponding to the characters of the original language and the character codes corresponding to the characters of the translation target language included in the conversion table  320  are used. The character codes not corresponding to either the characters of the original language or the characters of the translation target language included in the conversion table  320  correspond to a plurality of character codes that are not the test objects. 
     For the purpose of obtaining the information regarding the original character strings, the character codes corresponding to the characters of the translation target language included in the conversion table  320  are each associated with the character shape of the character of the original language that has the character of the translation target language corresponding to the relevant character code as the “converted-to” character upon generation of the test resource file  340 . In this manner, it can be configured such that the character strings included in the original resource file  310  are each displayed in the original language on the output screen of the test object program that performs processing by referring to the test resource file  340  of the present invention. Further, the character codes corresponding to the characters of the original language are each assigned with the character shape of the character corresponding to the relevant character code. This ensures that the perfect information regarding the original character strings can be obtained even in the presence of hard-coded character string(s). Meanwhile, the character codes that are not the test objects are each associated with a same character shape to facilitate identification. It can be said that they are the character codes of the garbled characters, as explained above in conjunction with the garbled character detection font  380 . That is, in the display screen using the reverse font, it is not only possible to obtain the information regarding the original character strings, but also possible to detect the garbled characters. In this regard, the same character shape is preferably a conspicuous character shape such as a postal mark, or a conspicuous and less frequently used character shape. 
       FIG. 9A  shows, as an example of the reverse font  385 , a table  850  of the reverse font in the case of generating a test resource file  340  based on the conversion table  405  shown in  FIG. 4B , with English as the original language and Japanese as the translation target language. In the table  850 , to facilitate understanding, the character codes of the characters of the original, English language and the corresponding characters are added in the leftmost two columns. Accordingly, the central column of the table  850  shows the character codes of the reverse font  385  and the rightmost column shows glyphs assigned to the corresponding character codes. The column therebetween shows glyphs in a regular font. In the table  850 , the character codes U+3000 to U+FFEA are those corresponding to the Japanese characters included in the conversion table  405 . As explained above, they are the character codes as the test objects, so that they are assigned with the character shapes of the original English characters before conversion. 
     Referring to the portion  855  in  FIG. 9A  delimited by a dotted line, the character code U+8868 is assigned with the character shape of
     “         ”
 
in the regular font. In the reverse font  385 , the character code U+8868 is assigned with the character shape of “S”, which is the character corresponding to the character code U+0053 of English that has the character code U+8868 as the “converted-to” code. In the table  850 , the character codes U+0020 to U+007E are those corresponding to the English characters. They are the character codes corresponding to the characters of the original language as explained above, and thus, the character shapes of the characters of the original language are assigned thereto without modification. The other character codes in the table  850  correspond to a plurality of other character codes in Unicode. They correspond to the garbled characters as explained above, so that the character shape of the postal mark is assigned thereto in this example. It should be noted that the number of rows in the table  850  does not indicate the actual number of the character codes.
   

       FIG. 9B  shows a display screen  860  in the case where the processed results of the test object program that read the test resource file  410  shown in  FIG. 4C  at the time of activation are displayed using the table  850  of the reverse font. As seen in  FIG. 9B , the character strings are displayed in the original, English language except for the portion of the button  880  having the garbled characters, and the screen is approximately the same as the original display screen  110  shown in  FIG. 1C . As such, when using the reverse font  385 , the tester can readily detect the garbled characters while he/she can confirm the original character strings without the need to open the original resource file. 
     The sort font  390  will now be explained that is used for determination of validity of the sort result of the character strings according to the order of the characters defined in the translation target language as the second language. In the determination of validity of the sort result, the character codes corresponding to the characters of the translation target language included in the conversion table  320  correspond to a plurality of character codes as the test objects. Since the test resource file  340  of the present invention is created by converting all the characters of the original language included in the original resource file  310  to the characters of the translation target language based on the conversion table  320 , the output of the test object program that read the test resource file  340  must include the characters of the translation target language included in the conversion table  320 . Accordingly, the character codes corresponding to the characters of the original language as the first language, as well as the character codes not corresponding to either the characters of the original language or the characters of the translation target language included in the conversion table  320 , correspond to a plurality of character codes that are not the test objects. 
     In the sort font  390 , in order to facilitate determination on the screen as to whether the character strings of the translation target language are sorted correctly according to the order of the characters defined in the translation target language, the character codes as the test objects are each associated with a character shape that indicates the order defined for the character corresponding to the relevant character code. Meanwhile, the character codes that are not the test objects are each associated with a same character shape, which is preferably a less frequently used character shape, an inconspicuous character shape, or a less frequently used and inconspicuous character shape, such as a hollow square or a blank. 
       FIG. 10A  shows, as an example of the sort font  390 , a table  900  of the sort font in the case of creating a test resource file  340  using the conversion table  405  shown in  FIG. 4B  with English as the original language and Japanese as the translation target language. In the leftmost column of the table  900  are the character codes, and in the rightmost column are glyphs in the sort font assigned to the corresponding character codes. In the central column of the table  900 , glyphs in a regular font are added for reference. In the table  900 , the character codes U+3000 to U+FFEA are those corresponding to the Japanese characters included in the conversion table  405 . They are the character codes as the test objects as explained above, and thus, they are each assigned with the character shape indicating the order defined for the relevant character. It is noted that the “order of the characters defined in the translation target language” may be any order; how to define the order of the characters depends on which kind of test is to be conducted. Herein, the order of the character codes of the Japanese characters included in the conversion table  405  is employed. For the character codes such as the character code U+FFEA to which symbols are assigned in the glyphs of the regular font, an inconspicuous character shape such as a hollow square may be assigned instead of the number like (93). 
     In the table  900 , the character codes U+0020 to U+007E are those corresponding to the English characters. The other character codes in the table  900  correspond to a plurality of other character codes in Unicode. Since they are the character codes that are not the test objects as described above, they are each assigned with a hollow square character shape in this example. It should be noted that the number of rows in the table  900  does not indicate the actual number of the character codes.  FIG. 10B  shows a display screen  905  in the case where the processed results of the test object program that performs processing by referring to the test resource file  410  shown in  FIG. 4C  are displayed using the table  900  of the sort font. Referring to  FIG. 10B , the characters of the character strings to be listed on a list box  915  are all displayed as the numbers. Thus, determination as to whether a sort result when executing the sort command by clicking on the button  920  (see the button  125  in  FIG. 1C ) is correct or not can readily be made by checking the numbers corresponding to the first characters of the respective character strings (if they are the same number, the numbers of the following characters; this applies hereinafter as well). As such, when using the sort font  390 , it is readily possible to determine whether the sorting is correct or not even if the translation target language has a great number of types of characters. 
     The four fonts described above, i.e., the hard-coded character detection font  375 , the garbled character detection font  380 , the reverse font  385 , and the sort font  390 , can be created for example in the following manner. The existing font file is copied and given a new name. The newly created font file is opened using a commercially available font editor or the like, and the character shapes to be assigned to the character codes are edited as appropriate to create any of the above-described fonts of the present invention. It is of course possible to create the font of the present invention from the beginning by using a font editor. As for the character coding scheme designated when creating a font according to the present invention, any character coding scheme may be selected as long as it includes the character set of the original language and the character set of the translation target language. 
     Hereinafter, an example of a process flow for testing a test object program by using a mock-translated resource file and a plurality of fonts prepared for respective test categories according to an embodiment of the present invention will be explained with reference to the flowchart shown in  FIG. 11A . Firstly, as pre-processing, a test resource file  340  is stored in the second storage unit, and a plurality of fonts prepared for the respective test categories are stored in the third storage unit together with a regular font, in such a manner that they can be referred to by the test object program execution unit  355 , the display screen creation unit  360  and the font selection unit  365 . In order for the fonts to be actually used, it is necessary to install the fonts into a computer that uses the fonts. The installing method will be explained later in conjunction with an implementation example. As the processing starts, firstly, the test object program execution unit  355  reads the test resource file  340  from the second storage unit (step  600 ). The test object program execution unit  355  performs various processing of the test object program by referring to the test resource file  340  (step  605 ), and outputs the processed results (step  610 ). 
     The display screen creation unit  360  receives the processed results from the test object program, and creates a display screen of the processed results by using a default font included in the third storage unit (step  615 ). At this time, the display screen creation unit  360  temporarily stores the processed results received from the test object program in a buffer. The display screen creation unit  360  transmits the created display screen to a display device (step  620 ). The font selection unit  365  waits for an input from the user (step  625 ), and upon reception of the input, it determines whether the received input corresponds to a font selection request (step  630 ). If it is not the font selection request (step  630 : NO), the process is terminated here. If it is the font selection request (step  630 : YES), the font selection unit  365  confirms available fonts by referring to the third storage unit, and creates a display screen for font selection (step  635 ). The font selection unit  365  then transmits the created display screen for font selection to the display device to be displayed on the screen (step  640 ). 
     When the font selection unit  365  receives a designation of the font to be used from the user (step  645 ), it provides the display screen creation unit  360  with information regarding the type of the designated font. The display screen creation unit  360  reads the processed results of the test object program from the buffer, and newly creates a display screen of the processed results using the font selected by the user (step  650 ). The display screen creation unit  360  again transmits the created display screen to the display device (step  655 ). The process then returns to the step  625 . 
     Now, referring to  FIG. 11B , the process in the step  650  will be explained in detail. Firstly, the display screen creation unit  360  reads the processed results of the test object program from the buffer (step  660 ). The display screen creation unit  360  determines whether the read processed results include data to be processed next (step  665 ). If there is no data to be processed next (step  665 : NO), the process is terminated here. If there is any data to be processed next (step  665 : YES), the display screen creation unit  360  reads the data to be processed next from the processed results (step  670 ), and determines whether the data includes any character code (step  675 ). If it includes no character code (step  675 : NO), the display screen creation unit  360  creates a part of the display screen based on the data to be processed without modification (step  680 ). If it is determined in the step  675  that at least one character code is included, the display screen creation unit  360  retrieves the character shape assigned to the relevant character code from the font designated by the user (step  685 ), and uses the retrieved character shape to create a part of the display screen based on the data to be processed (step  690 ). 
     Each font according to the present invention includes a plurality of first character codes that are to be the test objects, a plurality of items of first character shape information associated one for one with the first character codes according to a first rule, a plurality of second character codes that are the other character codes of a prescribed character coding scheme, and a plurality of items of second character shape information associated one for one with the second character codes according to a second rule. Accordingly, in the case where any font of the present invention is designated in the step  645  shown in  FIG. 11A , if the character code included in the data to be processed is the first character code that is the test object, then the display screen creation unit  360  retrieves from the font the first character shape information assigned to the relevant first character code according to the first rule, and uses the information for screen display. If the character code included in the data to be processed is the second character code that is not the test object, the display screen creation unit  360  retrieves from the font the second character shape information assigned to the second character code according to the second rule, and uses the information for screen display. Accordingly, on the display screen, the first character code as the test object and the second character code that is not the test object are displayed in a distinguishable manner. After the step  680  or the step  690 , the process returns to the step  665 . 
     Hereinafter, an implementation example of the present invention will be described with reference to  FIGS. 12-14 .  FIG. 12  shows an implementation example of a system  950  implementing the present invention. The system  950  includes a Web server  970 , a storage device  955  connected to the Web server  970 , a client  975  connected to the Web server  970  via a network, and a storage device  980  connected to the client  975 . The storage device  955  includes a Web application  960  as a test object program, and a test resource file  965 . The storage device  980  includes a Web browser  985  and a plurality of fonts  990  prepared for the respective test categories. 
     The Web server  970 , when receiving a processing request from the client  975  via the network, activates the Web application  960  that executes the processing. Further, when receiving processed results from the Web application  960 , the Web server  970  transmits the processed results to the client  975  who requested the processing via the network. The Web application  960  as the test object program is loaded to a RAM of the Web server  970  from the storage device  955 , and executed by a central processing unit (CPU) of the Web server  970 , to thereby function as the test object program execution unit  355  shown in  FIG. 3 . The Web application  960  reads the test resource file  965  from the storage device  955  at the time of activation, to execute the requested processing by referring to the relevant test resource file  965 . The processed results outputted from the Web application  960  are passed to the Web server  970 . 
     The client  975  activates the Web browser  985  in response to a request from a tester who tests the Web application  960 . The Web browser  985  is loaded from the storage device  980  to a RAM of the client  975 , and executed by a CPU of the client  975 , to function as the display screen creation unit  360  and the font selection unit  365  shown in  FIG. 3 . The Web browser  985 , in response to an input of the tester, requests the processing provided by the Web application  960  from the Web server  970 . When receiving the processed results from the Web server  970 , the Web browser  985  serving as the display screen creation unit  360  creates a display screen of the processed results using a default font, and displays it on a display of the client  975 . 
     When receiving a font selection request from the tester, the Web browser  985  serving as the font selection unit  365  acquires a list of available fonts by referring to the fonts stored in the storage device  980  or by calling a function for acquiring available font names, and displays a dialog box for font selection on the display of the client  975 . When receiving a designation of the font to be used from the tester, the Web browser  985  uses the designated font to display again the processed results on the display of the client  975 . 
     In order to allow the Web browser  985  to refer to the plurality of fonts  990  prepared for the respective test categories according to the present invention, it is necessary to install the fonts  990  into the client  975 . Such installation is carried out by an operating system (OS) running on the client  975 . For example, when using Microsoft Windows (registered trademark) XP as the OS, the fonts are installed using the Fonts in the Control Panel functioning to add, modify and manage the fonts of the computer. There is “Install new font” prepared in the file menu of the Fonts. When using Microsoft Windows (registered trademark) versions before XP, the font management software called Adobe Type Manager (ATM) can be used. Once the ATM is installed into the computer, all that is needed is to drag and drop the font file into the system folder and restart the computer. 
     A process flow of the system  950  will now be explained with reference to the flowchart in  FIG. 13 . The Web server  970  waits for a request from the client in the step  700 . The Web browser  985  as the client waits for an input from the tester (step  705 ). When receiving the request for the processing provided by the Web application  960 , the Web browser  985  transmits the request to the Web server  970  (step  710 ). In response to reception of the request (step  715 ), the Web server  970  activates the Web application  960  (step  720 ). Upon activation, the Web application  960  reads the test resource file according to the present invention (step  725 ), and refers to the test resource file to execute the requested processing (step  730 ). The Web application  960  outputs processed results and passes them to the Web server  970  (step  735 ). 
     In response to reception of the processed results (step  740 ), the Web server  970  transmits the processed results to the Web browser  985  (step  745 ). When receiving the processed results (step  750 ), the Web browser  985  creates a display screen of the processed results using a default font (step  755 ), and displays the same on the display of the client  975  (step  760 ). The Web browser  985  waits for an input from the tester (step  765 ). Upon reception of the input from the tester, the Web browser  985  determines whether the input corresponds to a font selection request (step  770 ). If it is the font selection request (step  770 : YES), the Web browser  985  refers to the storage device  980  to check the available fonts, and creates a list of available fonts including the plurality of fonts prepared for the respective test categories according to the present invention (step  775 ). 
     The Web browser  985  uses the created list to display a dialog box for font selection on the display of the client  975  (step  780 ) (see  FIG. 14 ), and waits for a designation of the font from the tester. In response to an input of the font designation from the tester (step  785 ), the Web browser  985  uses the designated font to display the processed results again (steps  790 ,  795 ). In the case of NO in the step  770 , i.e., if the input from the tester is not the font selection request, the process proceeds to the step  800 , where the Web browser  985  executes other processing. After the step  795  or the step  800 , the process returns to the step  765 , where the Web browser  985  again waits for an input from the tester. While the processes in the steps  765  through  795  are repeated, when the fonts are switched by the tester among those prepared for the respective test categories according to the present invention, the corresponding display screens as shown in  FIGS. 7B ,  8 B,  9 B and  10 B are displayed on the display of the client in turn. 
       FIG. 15  shows an example of a hardware configuration of the apparatus  300  for creating a test resource file according to the present invention.  FIG. 15  also shows an example of a hardware configuration of the apparatus  350  for testing a test object program using a mock-translated resource file and a plurality of fonts prepared for the respective test categories, according to the present invention.  FIG. 15  may also be regarded as an example of a hardware configuration of a computer when implementing the function of the apparatus  300  and the function of the apparatus  350  in a single computer. In the system  950  explained referring to  FIGS. 12-14 , the apparatus  350  is configured with two computers, i.e., the Web server  970  and the client  975 . In such a case, the hardware configuration shown in  FIG. 15  may be regarded as an example of the hardware configuration of each of the Web server  970  and the client  975 . 
     A system  1000  includes: a CPU peripheral portion that includes a CPU  1010  and a RAM  1040  connected to each other by a host controller  1015 , a graphic controller  1020 , and a display device  1025 ; an input/output portion that includes a communication interface  1070 , a hard disk drive  1050  and a CD-ROM drive  1060  that are connected to the host controller  1015  by an input/output controller  1030 ; and a legacy input/output portion that includes a super I/O controller  1080  connected to the input/output controller  1030 , a flexible disk drive  1090  connected to the super I/O controller  1080 , a flash ROM  1100 , and a keyboard mouse controller  1110 . 
     The host controller  1015  connects the CPU  1010  with the RAM  1040 , the CPU  1010  accessing the RAM  1040  at a high transfer rate. The CPU  1010  operates based on a program stored in a hard disk to control the portions. The program for testing the test object program according to the present invention is stored in a recording medium such as an optical recording medium like a flexible disk, CD-ROM, DVD or PD, a magneto-optical recording medium like an MD, or a semiconductor memory like an IC card, and provided to a user. Alternatively, the program for testing the test object program may be downloaded from an external computer via the network. Similarly, the plurality of fonts prepared for the respective test categories according to the present invention are stored in the recording medium such as the optical recording medium like a flexible disk, CD-ROM, DVD or PD, the magneto-optical recording medium like an MD, or the semiconductor memory like an IC card, or alternatively downloaded via the network, and provided to the user. 
     The input/output controller  1030  connects the host controller  1015  with the communication interface  1070 , the hard disk drive  1050  and the CD-ROM drive  1060 , which are relatively high-speed input/output devices. The communication interface  1070  communicates with another computer via the network. The CD-ROM drive  1060  reads a program or data from a CD-ROM, and provides the same to the CPU  1010  via the input/output controller  1030 . The input/output controller  1030  is connected with a flash ROM  1100  and with the relatively low-speed input/output devices such as the flexible disk drive  1090  and the keyboard mouse controller  1110 . The flash ROM  1100  stores a boot program executed by the CPU  1010  upon activation of the device system  1000 , a program dependent on hardware and others. The flexible disk drive  1090  reads a program or data from a flexible disk, and provides the same to the super I/O controller  1080  via the RAM  1040 . The super I/O controller  1080  connects the flexible disk and various input/output devices via parallel port, serial port, keyboard port, mouse port and the like.
