UTF-8 数学記号

範囲：十進数 8704-8959、十六進数 2200-22FF

HTMLで特殊文字を表示したい場合は、以下のHTMLエンティティを使用できます。

キャラクターにHTMLエンティティがない場合、十進数（dec）または十六進数（hex）の参照を使用できます。

例

<p>私は ∑ を表示します</p>
<p>私は ∑ を表示します</p>
<p>私は ∑ を表示します</p>

次のように表示されます：

私は ∑ を表示します
私は ∑ を表示します
私は ∑ を表示します

自分で試してみてください

古いブラウザでは、下表のすべてのHTML5エンティティをサポートしていない可能性があります。

Chrome と Opera のサポートは非常に良いですが、IE 11+ と Firefox 35+ ではすべての実体がサポートされています。
