Subject: (Vcharset_jis_x0208): New variable in UTF-2000.
X-Git-Tag: r21-2-44-utf-2000-m0_18-jis-x0208-common~11
X-Git-Url: http://git.chise.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=76d414ef9e9609c7a82fd80ba601d83e286db504;p=chise%2Fxemacs-chise.git-

(Vcharset_jis_x0208): New variable in UTF-2000.
(Qjis_x0208): Likewise.
(decode_builtin_char): Prefer XCHARSET_MAX_CODE(charset) than
XCHARSET_FINAL(charset).
(charset_code_point): Modify condition for final-byte based
builtin-chars.
(syms_of_mule_charset): Add new symbol `=jis-x0208' in UTF-2000.
(complex_vars_of_mule_charset): Add new coded-charset `=jis-x0208' in
UTF-2000; specify `=jis-x0208' as the mother of
`japanese-jisx0208-1978', `japanese-jisx0208' and
`japanese-jisx0208-1990' in UTF-2000.
