Roundcube webmailer で ISO-2022-JP-MS >>PHP 

taka2 さんのところのパッチ( http://taka2.info/20111222/roundcube/ )を参考にいろいろいじってたりします、が

ISO-2022-JPをメール作成画面で選択しても、ISO-2022-JP-MSを使うようにしなければならないため、ちょっと処理を変える必要があります。
※メモ:ISO-2022-JP-MSはPHP5.2.1からはふつうに使えて、それ以前は要パッチ
※あにゃログ- SKK と波ダッシュと全角チルダと私 なども読むとより楽しめるかもしれない http://www.sopht.jp/blog/index.php?/archives/455-SKK.html
