There are other, more serious cases of presentation ambiguity (e.g. tabs vs. spaces), yet nobody suggests to ban tabs from the language for that reason.

But we have suggested banning mixed tabs and spaces (rather than just recommending against it), which is something that can be automatically verified.

I don't think this scenario is all that unlikely. A program is initially written by a Russian programmer who uses his own version of "a" as a variable name. Later an English-speaking programmer makes some changes, and uses an ascii "a". Now there are two subtly different variables called "a" in different parts of the program.
