Unicode freaks it out

[GanerCodes]

let 𝒪 = 1;

turns into

let𝒪 = 1;

despite 𝒪 being a valid JS identifier.
(if i had to guess, it might be due to getting the length of a string with in utf-16 by accident?)

no just the regex stuff is completely scuffed. i fixed it by:

1. pip install regex which provides more features
2. replace all instances of import re\n with import regex as re\n
3. in /python/jsbeautifier/javascript/acorn.py replace _nonASCIIidentifierStartChars and _nonASCIIidentifierChars with:

_nonASCIIidentifierStartChars = r"\p{L}\p{Nl}"
_nonASCIIidentifierChars      = r"\p{L}\p{Nl}\p{Nd}\p{Pc}\p{Mn}\p{Mc}"

4. struggle to install with pip for an hour and give up and just cp -r jsbeautifier into /usr/lib/python3.14/site-packages/ because i can't figure out these build scripts

also no promises i got those regexes exactly correct but it works for my stuff at least

here's a link to a version with this fixed if it's needed, it has the changes i described

@GanerCodes
What codepoint is "𝒪"?

Is this due to the copied acorn regex pattern being wrong?
The same behavior occurs in on https://beautifier.io/ , so this isn't specific to the python implementation.
