Stray thought: this sounds like something that would be fixed (on Unix)
by setting the locale-controlling environment variables, so that your
build happens in a local using UTF-8 as its encoding; hopefully, that
would then coax the compiler into using this by default and not getting
upset.  I'm not sure how that works on MS-Windows, but I'd just set
LANG=en.UTF-8 in my environment on any Unix; this would then only affect
the process in which I set it.  So it might be worth seeing if you can
do that (or something equivalent) for the process that runs configure &&
make for you.

If that *does* work ... perhaps we should hack this into our Makefiles,
