You're right. I meant to say "..., by default" (since I don't use ":set
arabic", delcombine was not set).

GTK+ (not Vim GTK+ front-end) handles most of them. Supporting them
doesn't look that hard (but maybe a bit slow). I think the combinations
and the resulting character can be saved in a table so that arabic.c
(needs changing mbyte.c) can look it up. But it is probably not worth
the effort.

What I'm saying is there is a lot of them... See 0xfbea till 0xfdfd
unicode chars. But I'm not sure, maybe LAM-ALEF combination is special
in Arabic.
Anyway, I think everyone (arabic.c users) is happy with the current
state.
