For this, Unicode relies on the application or on the operating system. Unicode does not translate the text in your applications into localized versions. Unicode does not translate your data from one language to another. Unicode Encodings Unicode can be encoded in one of several different formats. Its fixed width means that the application does not need to determine the boundaries of the data and, therefore, UCS-2 is well suited for processing character data in an application.
Different characters are one, two, or three bytes in length.
Asian ideographs are encoded as three-byte characters. Accented European characters are encoded as two-byte characters. Unicode is a single, very large character set that supports over 6,000 characters used in the world's written languages. Although the Japanese DBCS encodings are also two-byte encodings, they are an entirely different encoding scheme from Unicode. Nor are the DBCS character sets a subset of Unicode.
