What are all the languages use double byte characters?

Can anyone point me to the list of languages that use double byte characters?

Thanks,

DBCS is a property of a code page. A code page needs double-byte characters when it needs to encode more than 128 non-ASCII glyphs. On Windows that's

• 932, Japanese
• 936, Simplified Chinese
• 949, Korean
• 950, Traditional Chinese

There are probably more, IBM and Oracle defined their own. This is all a bad memory, Unicode rules.
