AFAICS the most that could accomplish is to make failures more obvious;
it wouldn't actually fix anything. I don't think that's worth the
runtime penalty it would incur.
What we *ought* to be doing is trying to figure a way to detect and
disallow inconsistent locale/encoding combinations. We've avoided that
because there seems no general platform-independent way to find out the
encoding expected by a locale. But surely we could manage to make it
work at least on glibc and Windows, which would be a step ahead of doing
nothing.
