How about if we start by warning about any Lisp symbol whose name uses
characters from more than one script for non-punctuation characters?
puny.el has a function that solves a similar problem, which could be
used as a starting point.

We could make this an opt-in feature if the warnings are deemed to be
a potential annoyance.
