Japanese Character Sets

The supported Japanese character sets include:

JIS X 0212–1990 is not supported in the ja_JP.PCK locale. JIS X 0213:2004 is supported in the ja_JP.UTF-8 locale only. Not all characters defined in the JIS X 0213:2004 are available. Only those characters defined in the Unicode 4.0 character set are available.

Vendor-defined characters (VDC) and user-defined characters (UDC) are also supported. VDCs occupy unused (reserved) code points of JIS X 0208–1990 or JIS X 0212–1990. UDCs occupy the same code points as VDCs, except those code points allocated for VDCs.
