You misunderstood my point: >> There is only ... that should ever be allowed... What I am saying is someone decides to code in a non-english language (which is completely reasonable) they should define a subset of unicode characters that is acceptable. Additionally, the allowed characters should not permit tricks like these. As for excluding entire languages... well, yes. This is already the case today. But OTOH it's not like understanding what "if" means gives you any special advantage in programming.
