language support and gtk-win32

[John Emmas <johne53 tiscali co uk>]

An app I'm working on offers language support via gtk-i18n.  AFAIK it works fine on OS-X and Linux.  On Windows we use the same language modules (".mo" files) but gtk-win32 doesn't seem to like them (or at least, it doesn't like the French one, which is the only one I've tested so far).  I haven't yet got as far as finding out which gtk function is complaining but I do know that this hex sequence:-

 0xC3  0xA9

is being deemed to be an invalid UTF-8 sequence.

I won't personally be dealing with the problem but before I pass it on, I'd just like to find out if those two characters do or don't constitute valid UTF-8.  Is that the sort of question that someone here could answer?  Thanks.
