That is just what many users (including, in some environments, me)
cannot do *because* of the extended charset.

I can't see whether the I have an ASCII o or a Cyrillic o, because
they look the same, even though they aren't.  If the whole think is in
Cyrillic, I may notice; if only a few identifiers are, I probably
won't notice at least until I've already saved it (and possibly broken
it, depending on how unicode-unaware my editor is).

A warning would indeed be sufficient.
