g_utf8_validate() assumes the encoding is UTF8. It doesn't work on
anything you'd normally pass to g_convert().

The purpose of this is to ensure you have valid UTF8, for example when
loading a file you expect to be UTF8, or in g_return_if_fail()
statements. If you pass invalid UTF8 to GTK, GTK will probably crash
sooner or later.

We aren't trying to be complete. We are UTF8 bigots. You have to use
iconv() or g_convert() to use funky charsets.
