This would ignore all non-ascii identifier symbols, i.e. const func = (a = _µµ_µµ_) => {}, would that be fine?

IMO we shouldn't support non-ascii identifier symbols. Moreover, our eslint config won't even allow such identifiers.

@SemenchenkoVitaliy the rule you linked doesn't check if the identifier contains Unicode characters with code points values higher than 0x7F, it just checks that the identifier is in camel case, and it is possible to use camel case in other languages. As for using underscores in the middle of the identifier with this rule, they can be used when everything else is in uppercase (as in constants), for example:

const ПРИВІТ_СВІТЕ = 'Hello, world!';
