Subject: (Vdecomposition_feature_list): New variable when UTF2000 is defined.
X-Git-Tag: r21-4-22-chise-0_25-6^20~503
X-Git-Url: http://git.chise.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1cba3ca6672037dc9a122d27ecd7bb3987d9d09b;p=chise%2Fxemacs-chise.git

(Vdecomposition_feature_list): New variable when UTF2000 is defined.
(char_encode_utf8): Refer variable `decomposition-feature-list'
