In this case, in the case a character font corresponding to 'open' does not exist, a character-string 112 of 'flowers open' is outputted by replacing it with a character code for expressing the reading. In such a way, in the case a first character font corresponding to a first character code does not exist, a second character font corresponding to a second character code for showing the reading of a character shown by the first character code is outputted. Accordingly, even if the corresponding character font does not exist in a character code table, the original character can be understood without allowing the information quantity to be lacking.
