Subject: (LEADING_BYTE_HIRAGANA_JISX0208): New macro.
X-Git-Tag: r21-2-19-utf-2000-0_8-2~26
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=d95830511340e0b278acf32b8c3bb2d8632a8966;p=chise%2Fxemacs-chise.git.1

(LEADING_BYTE_HIRAGANA_JISX0208): New macro.
(LEADING_BYTE_KATAKANA_JISX0208): New macro.
(struct Lisp_Charset): Add `byte_offset'.
(CHARSET_BYTE_OFFSET): New macro.
(XCHARSET_UCS_MIN): New macro.
(XCHARSET_UCS_MAX): New macro.
(XCHARSET_CODE_OFFSET): New macro.
(XCHARSET_BYTE_OFFSET): New macro.
(MIN_CHAR_HIRAGANA): New macro.
(MAX_CHAR_HIRAGANA): New macro.
(MIN_CHAR_KATAKANA): New macro.
(MAX_CHAR_KATAKANA): New macro.
(MAKE_CHAR): Modify for new coded-charset definition; use
`XCHARSET_UCS_MIN', `XCHARSET_UCS_MAX', `XCHARSET_CODE_OFFSET' and
`XCHARSET_BYTE_OFFSET'.
