AIUI, the locale is determined and kept in Xlib, and so is that of the
client.  However, this is determined by the locale at startup using
the usual setlocale() call.  If you want to change the locale of
XEmacs and Xlib, you need to call setlocale again.  But this won't
affect resources already bound in the widgets.
