[swift-evolution] Prohibit invisible characters in identifier names

[Charlie Monroe]

Sure, but if you want to have translated identifiers, there's really no other (better) option unless you want to create ABI incompatible code (given that Swift 4 has a finalized ABI) that only runs on your localized system.

For one to lear programming without actually knowing any English would require the language to have localizable identifiers. Can you imagine those? Given how much time is put here to standardize the naming of a few methods in the standard library, how would it look in other languages?
