If we do this, I will have to bow out of maintaining any code I've written with Unicode characters. There is a lot of numerical code that simply too hard for me to read if I'm forced to do an extra layer of transliteration for the sake of charset purity. I agree that the homograph problem is an issue, but it is something that is not hard to check in practice so long as one is consistent within the same scope.
