This page shows the FAQ about JIS X0213 standard.
JIS X0213, "7-bit and 8-bit double byte coded extended Kanji sets for information interchange," is new Japanese national standard of coded character set established by JISC (Japanese Industrial Standards Committee) in January 2000. It enumerates 11,223 characters which extends 4,344 characters from JIS X0208 standard. It consists of 10,040 Kanji (ideographic) characters and 1,183 non-Kanji (non-ideographic) characters. These characters are arranged in two planes of a 94-row-by-94-cell matrix. Also, as informative annex, three encoding methods are defined as the extension from existing defacto encodings, that is, Shift JIS, EUC-JP and ISO-2022-JP.
There are several JIS coded character set standards. JIS X0201 is the single byte coded character set which adapts ISO/IEC 646 standard in Japan. JIS X0208, JIS X0212 and JIS X0213 are the double byte coded character sets, and JIS X0221 is the multi-byte coded character set which is corresponding to ISO/IEC 10646. JIS X0208 is the primary double byte coded character set used for Japanese. Although both of JIS X0212 and JIS X0213 Kanji standards have been established as the supplement to JIS X0208 standard, their scopes of source character set are different.
Almost all characters in JIS X0213 have corresponding character on Unicode / ISO/IEC 10646. Only few non-Kanji characters are represented by composite sequence on Unicode / ISO/IEC 10646. All kanji characters are mapped to any block of CJK Unified Ideographs, CJK Compatibility Ideographs, CJK Unified Ideographs Extension-A or CJK Unified Ideographs Extension-B on Unicode 3.1 / ISO/IEC 10646 Part-1 and Part-2, or mapped to CJK Compatibility Ideographs (Extension) currently being reviewed as one of Unicode 3.2 enhancement / the amendment 1 of ISO/IEC 10646-1:2000. Similarly, non-kanji characters are mapped to ISO 10646-1:2000 and its amendment 1.
