I think in this test case, with the ΡΎ character coming from DejaVu Sans
(while the other characters come from DejaVu Sans Mono), the results of
just clipping will be kinda ugly.  But it's worth a shot and see how it
looks in practice -- perhaps it'll be good enough.

I really wonder what gnome-terminal is really doing here.  I downloaded
the sources, but it looks like all the magic happens down in the Pango

(domestic pets only, the antidote for overdose, milk.)
