The most popular codesets are a series called ISO 8859. To identify all ideographic symbols in Asian languages, such as Chinese and Japanese, character encoding requires more than one byte. Numerous codesets using multibyte character encoding, which is not supported by the ISO 8859 series of codesets, have been developed for Asian languages. As previously mentioned, the locale specified on your system influences how information is processed and displayed. The following sections describe the items in this list.
Collation always follows a set of rules.
Some languages require collation rules that are not used in English. Multilevel Some languages include groups of characters that all sort to the same primary location. Additional sort rules apply to order characters within the same group. Words that begin with these characters collate the same location, at which point words are sorted within the group. In some languages, certain single characters are treated as if they were two characters.
