Subject: (charset_code_point): Merge code about builtin characters into code
X-Git-Tag: r21-2-43-utf-2000-0_18-n4~13
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=c22b401ea7242f5f796759d1abe3c8c3269d27b5;p=chise%2Fxemacs-chise.git.1

(charset_code_point): Merge code about builtin characters into code
about mother charsets; don't use `range_charset_code_point'.
(range_charset_code_point): Deleted.
