Maybe in the future more languages/ tools will have the concept of per-project character sets, as opposed to trying to wrangle all possible Unicode ambiguity problems.
I suppose then the problem is how to permit exceptions when integrating with some library written in another (human) language.
Or we could just accept English as the lingua franca of computing and not try to support anything other than ASCII in source code (at least not outside string constants). That way not only do we eliminate a whole class of possible exploits but also widen the number of people who can understand the code and spot issues.
