As far as I understand, this only adds Cyryllic to basic alphanumeric characters. That still leaves quite a number of characters in other scripts as well as diacritics in Latin, that should be accepted based on the same principle. On top of that I'd argue the
\s
excludes a few problematic variants of whitespace that should in fact be escaped.My proposition is the following:
/[^\p{L}\p{N} \.-_]/gu
That is:
/gu
for full unicode\p{L}
- any kind of letter from any script\p{N}
- any kind of numeric character in any script\.-_
- a literal whitespace, a dot, a dash and an underscoreWould bruno support that?

I agree with expanding that regex to exclude more characters. Also technically that regex variable should probably be called
invalidChars
.
