@dalias I'm not sure that counts as 'incompatible.' It means that particular script doesn't have that nuance. But if we're talking language & not script, the terms are going to be translated anyway - so the original case is irrelevant.
As for aesthetics, I've never understood the argument against it.
@FeralRobots No, I mean if you're trying to write identifiers in your own language that doesn't have case, then there is no way to write them in camelcase.
I'm talking about actual non-English/non-Latin source files, not translating identifier names into another language when talking about them.
