From 8f9531ff139af52e1899061de2111d170ab51982 Mon Sep 17 00:00:00 2001
From: MORIOKA Tomohiko <tomo.git@chise.org>
Date: Wed, 20 Jan 2010 03:03:35 +0000
Subject: [PATCH] (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.
