【JavaScript】アスキーの特殊文字を全て表す正規表現

Webアプリケーションでアスキーの特殊文字32文字を入力したら、「特殊文字は入力不可」と表示させる。
このようなことをしたい場合は、32個のアスキー特殊文字を表す正規表現オブジェクトを生成する必要がある。
この32文字の特殊文字を表す正規表現を1文字づつ書くと長くなる。
しかし、32個のアスキー特殊文字を正規表現クラス[]を用いて文字範囲を指定して短く書くことができる。
!から/まで文字の範囲を指定する。
:から@まで文字の範囲を指定する。
[から`まで文字の範囲を指定する。
{から˜まで文字の範囲を指定する。
これにより短い正規表現で表せる。
[!-\/:-@[-`{-~]

/*

JavaScript:the good parts P87は間違えているな。
オライリーのJavaScript:the good partsの正誤表には書いていない。
10年以上前に買った本だけど、2023年3月2日にこの正規表現が間違っていることに気づいた。
全く気付かなかったわ。

(誤)?が抜けているな。
(?:!|"|#|\$|%|&|'|\(|\)|\*|\+|,|-|\.|\/|:|;|<|=|>|@|\[|\\|]|\^|_|`|\{|\||\}|~)
(正)?を追加した。
