The patch below makes the Lucid menu use fontsets to draw its text, so that
it's able to write non-ASCII (the set of chars supported is dependent on the
locale, and of course on the fonts).
I'm very much an idiot when it comes to X11 programming, xfaces.c, and
lwlib, so this might be riddled with bugs and misunderstandings, but after
some trial-and-error this not only works for me, but it even looks sensible
to me.
Any objection?
Stefan
PS: The use of XrmPutLineResource in xfaces.c seems amazingly brittle and
hackish, but that's what the rest of the code uses.
