Yeah, that is a concern. But as you say, it's already possible to
confuse rn with m (in many fonts) and i/l/1, and (on a different
level) Foo, foo, _foo, _Foo, and FOO, or movement_Direction and
movement_direction. If you saw one of those in one part of a program
and another in another, you'd have to consume an annoying amount of
mindspace to keep them separate.

Note, incidentally, that I said "alphabet" rather than the entire
Unicode character set. I do *not* support the use of, for instance,
U+200B 'ZERO WIDTH SPACE' in identifiers, that's just stupid :)
