I thought the most mode sane and modern language use the unicode block identification to determine something can be used in valid identifier or not. Like all the ‘numeric’ unicode characters can’t be at the beginning of identifier similar to how it can’t have ‘3var’.
So once your programming language supports unicode, it automatically will support any unicode language that has those particular blocks.
Sanity is subjective here. There are reasons to disallow non-ASCII characters, for example to prevent identical-looking characters from causing sneaky bugs in the code, like this but unintentional: https://en.wikipedia.org/wiki/IDN_homograph_attack (and yes, don’t you worry, this absolutely can happen unintentionally).
