Unicode is a two-byte encoding mode for all characters. Unicode characters are also called wide characters because they are wider than single-byte characters (more storage space is used ). Note that Unicode cannot be considered as MBCS. The unique feature of MBCS is that its characters are encoded in bytes of different lengths. A Unicode string use
