一般記号、数学記号、ギリシア文字の文字実体参照

一般記号、数学記号、ギリシア文字の文字の実体参照です。 HTML4.0の文字実体参照のための実体宣言を元にして表で表しています。

• [番号]は十進数表示の文字番号です。HTML4.0の基本文字セットはISO 10646-1 ですので、 ISO 10646-1のコードポイントの十進数表示ということです。
• [名前]は実体宣言での実体名、文字実体参照での名前です。
• [文字]は、ソースに実際にコード番号で数値文字参照してあります。よってブラウザやフォントに よって見え方が違ってきます。文字が表示出来ない場合、IEでは　・　、NNでは　?　と表示されます。 一般的な字形が見たい場合は ユニコードのサイトで見ることが出来ます。
• [コメント]はその文字の説明です。またユニコードでのコードポイントが U+ の次に 十六進数表記で書かれています。
