cnvk – Python で全角・半角・ひらがな・カタカナ等を変換する

Python で半角・全角の変換やカタカナとひらがなの変換などを行う簡単なモジュールを作ったので貼っておきます。他にも似たライブラリがありますがその一つとして。もしお役に立ちそうに思われた方はご自由にお使いください。で、何か不具合があれば教えてください♪

特徴

unicodedata よりは色々細かく指定できます。
追加の変換テーブルを指定するのも簡単です。
変換しない文字を指定できます。
変換方法は単純に replace です。正規表現ほか色々と試したんですが、たぶん早い方です。

ドキュメント

モジュール、関数に記載の doc を参照してください。
