Subject: [PATCH] (chise-tex-accent-macro-alist): New variable.
 (chise-tex-encode-region-for-utf-8-jis): Support Greek
 characters; don't encode U+00C5 and U+00E5; refer
 `chise-tex-accent-macro-alist'; use "\'{\^X}" instead of
 "\CircAcute{X}"; use "\~{\^X}" instead of "\CircTilde{X}";
 add setting for `HornTilde'. (chise-tex-decode-region):
 Decode "\={\i}".
