Subject: (Fget_char_attribute): If ATTRIBUTE is a name of charset, it is
X-Git-Tag: r21-2-19-utf-2000-0_11-0~18
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=2248f239a849ba497171378ea408aa942117aed8;p=chise%2Fxemacs-chise.git

(Fget_char_attribute): If ATTRIBUTE is a name of charset, it is
regarded as a charset.
(put_char_attribute): New function in UTF-2000.
(Fput_char_attribute): If ATTRIBUTE is a charset or a name of charset,
mapping-table of the charset is modified.
(Fdefine_char): New function in UTF-2000.
(Fset_charset_mapping_table): Use `put_char_attribute' instead of
`Fput_char_attribute'.
(syms_of_mule_charset): Add new function `define-char' and new symbol
`ucs' in UTF-2000.
(vars_of_mule_charset): Update `utf-2000-version' to 0.11 (Shiki).
