JIS X 0212 is aJapanese Industrial Standard defining acoded character set for encoding supplementary characters for use in Japanese. This standard is intended to supplementJIS X 0208 (Code page 952). It is numbered953 or5049 as anIBMcode page (see below).
It is one of the source standards for Unicode'sCJK Unified Ideographs.
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). This standard was intended to build upon the range of characters available in the mainJIS X 0208 character set, and to address shortcomings in the coverage of that set.
The standard specified 6,067 characters, comprising:
The following encodings or encapsulations are used to enable JIS X 0212 characters to be used in files, etc.
ESC $ ( D is used to indicate JIS X 0212 characters.No encapsulation of JIS X 0212 characters in the popularShift JIS encoding is possible, as Shift JIS does not have sufficient unallocated code space for the characters.
JIS X 0212 is calledCode page 953 by IBM, which includes vendor extensions.[2][3][4] The alternativeCCSID5049 excludes these 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 inUnix/Linux systems, and it is here that most implementations have occurred:
Many WWW browsers such as theNetscape/Mozilla/Firefox family,Opera, etc. and related applications such asMozilla Thunderbird support the display of JIS X 0212 characters in EUC-JP encoding, howeverInternet Explorer has no support for JIS X 0212 characters. Modernterminal emulation packages, such as theGNOME Terminal also support JIS X 0212 characters.
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 theHan unification which led to the unified set ofCJK characters in the initialISO 10646/Unicode standard. All the 5,801 kanji were incorporated.
Apart from the applications mentioned above, the JIS X 0212 standard is effectively dead. 2,743 kanji from it were included in the laterJIS X 0213 standard. In the longer term, its contribution will probably be seen to be the 5,801 kanji which were incorporated inUnicode.
