A locale that uses some non-UTF-8 multibyte encoding.

I wouldn't object. People who prefer non-UTF-8 multibyte locales might not like 
it (I'm not such a person so I can't say).

It's not merely the prompt that annoys me. It's that the prompt can occur long 
after the problem it diagnoses.

We could suppress the prompt in later occurrences if the user doesn't want to 
see it again.

A bit like, not exactly like. The point is that users often find it more 
convenient to see problems right away. For example, although an 
improperly-parenthesized Lisp buffer can be saved, it's still nice to have 
parenthesis-matching enabled as I type, so that I can see and fix parenthesis 
problems while they're still fresh in my mind.
