This question is identical to Regular Expressions: How to Express \w Without Underscore, except that the goal is to match characters in the letter (L) general category plus a specified set of additional characters.

For example, [-$\a\d]+ would match identifiers like $gâteau-Noël-19 but not $gâteau_Noël-19, if a hypothetical \a letter class existed. But for some bizarre and incomprehensible reason it does not.

So the clumsy substitute suggested in the previous question, [^\W_], works fine as a replacement for \a by itself. But how can it be combined with additional characters to form the above regular expression?

What variety of regex are you using? PCRE? – tshiono Jun 01 '20 at 02:04

Unicode property `\p{L}` matches any letter in any language, but it is not supported by all regex flavour. – Toto Jun 01 '20 at 08:57

Like `[\p{L}\d$-]+` https://regex101.com/r/9tfwVB/1 – The fourth bird Jun 01 '20 at 08:58
Python flavor - `\p` isn't supported directly, but it led to https://stackoverflow.com/questions/17595979/how-to-implement-pl-in-python-regex. Thanks! – Dave Jun 04 '20 at 20:40
