これは，Tkにおける非欧米文字集合を用いる言語に対するサポートについての\
|
||
サンプルです．ただし，下の表示においてあなたが実際にどのような表示を\
|
||
目にするかは，あなたの環境にどのような文字集合がインストールされているかに\
|
||
大きく依存します．また，対象となる文字集合がインストールされていない場合に\
|
||
どのような表示がなされるかもあなたの環境次第です．\
|
||
「コード参照」ボタンを押してソースを表示し，\
|
||
Unicodeout_SampleFrameクラスの@@fontの定義を書き換えて\
|
||
(ファイルの内容は変更されません)\
|
||
「再実行」ボタンのクリックを試してみてください．
|
||
スクリプトが可搬性を持つように，文字列は\\uXXXXという\
|
||
Tclのエスケープ表現を用いたUNICODE文字列で書かれています．\
|
||
文字列は，Tk::UTF8_Stringメソッドによって，\
|
||
「UTF8形式の文字列である」という\
|
||
エンコード情報付きの文字列オブジェクト\
|
||
(Tclのエスケープ表現の変換済み)に変換して\
|
||
ラベルウィジェットに渡している点に注意してください．
