Nah, don't touch the tests because of this.

I've some (rather horrible) patch that tries to make sense out of
LC_ALL or LC_CTYPE if set. And  if it isn't set, I'm currently
defaulting to 646//TRANSLIT (which is ASCII with translation of
some non-ASCII characters to ASCII art, like `(c)' for \xa9). But
Latin-1 may be a more usable default. Thanks for the suggestion.

(No, I'm not going to send this patch to cvs-ghc, it's really too
horrid).
