Subject: (decompose-char): New function.
X-Git-Url: http://git.chise.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f9531ff139af52e1899061de2111d170ab51982;p=chise%2Fuptex-chise.git

(decompose-char): New function.
(chise-tex-accents-macro-alist): Renamed from
`chise-tex-accent-macro-alist'; add some compound accents entries.
(chise-tex-encode-region-for-utf-8-jis): Omit local variable
`modifier-1'; use `decompose-char'; use
`chise-tex-accents-macro-alist' to avoid hard-coded codes.
