bug#56695: AW: bug#56695: A new and old font problem with Arabic

[address@hidden]

(set-fontset-font "fontset-default" 'arabic "DejaVu Sans Mono") das scheint zu 
gehen!

I tested it with:
--
(set-fontset-font "fontset-default" 'arabic "DejaVu Sans Mono")
--
in the init file. (I hope this is right way?)

It works, Emacs uses the font correctly.
And it seems that the positioning is then much better. The old problem is still 
there but not so often.

What I also noticed:
When I change the font with the same function 'set-fontset-font' but without 
restarting Emacs I get the old positioning problem immediately or after some 
typing and testing.
