Hmm... that's clearly the source of the problem (XLookupString can only
handle latin-1 locales, IIRC).

In the x_window function, in src/xfns.c (there are 3 versions of this
function :-( depending on whether or not we're using Gtk or some other
toolkit or no toolkit at all).

Could it be that use_xim is 0, somehow?
