JIS X 0212

In 1990 the Japanese Standards Association (JSA) released a supplementary character set standard: JIS X 0212-1990 Code of the Supplementary Japanese Graphic Character Set for Information Interchange (情報交換用漢字符号-補助漢字, Jōhō Kōkan'yō Kanji Fugō - Hojo Kanji).

JIS X 0212 is called Code page 953 by IBM, which includes vendor extensions.

[5] As JIS X 0212 characters cannot be encoded in Shift JIS, the coding system which has traditionally dominated Japanese information processing, few practical implementations of the character set have taken place.

As mentioned above, it can be encoded in EUC-JP, which is commonly used in Unix/Linux systems, and it is here that most implementations have occurred: Many WWW browsers such as the Netscape/Mozilla/Firefox family, Opera, etc.

Applications which support JIS X 0212 in the EUC coding include: The kanji in JIS X 0212 were taken as one of the sources for the Han unification which led to the unified set of CJK characters in the initial ISO 10646/Unicode standard.
