You need to use a compiled RegExp object with unicode: true argument:

String num = "(85)";
print(num.replaceAll(new RegExp(r"\p{P}", unicode: true), ""));

This outputs 85 as \p{P} is now treated as a punctuation proper matching Unicode property class regex.

thank Wiktor, this works like a charm – Jan Nov 13 '21 at 07:36
how about double quoted string and curly braces ? – Tony Hart Apr 07 '22 at 21:51
@TonyHart `\p{P}` only matches punctuation proper, if you need to match any punctuation and symbols, you need `[\p{P}\p{S}]`. – Wiktor Stribiżew Apr 07 '22 at 21:57
