Yes, the font is fine with OpenOffice, too.
It would be really great, if this could be fixed in context, so one
could typeset quran (and other traditional arabic) professionally. Would
be very valuable!

I uploaded a beta that might fix it, but it needs more testing. The
issue might have been introduced when support was added for more complex
ligature building, compare for instance this:
\starttext
\def\sample{نَسْتَعِينُ وَلَا الضَّالِّينَ}
\def\sample{نَسْتَعِينُ}
\def\sample{\Uchar"0643\Uchar"0644\Uchar"0651\Uchar"0627\Uchar"064E}
\setvariables
[otftracker]
[font=file:uthmantn1ver10.ttf,
size=24pt,
features=arabic,
direction=-1,
title=Feature Check,
sample=\sample]
\page
\setvariables
[otftracker]
[font=file:arabtype,
size=24pt,
features=arabic,
direction=-1,
title=Feature Check,
sample=\sample]
\stoptext
(So Kai needs to run some of his tests.)
Hans
ps. some of the somewhat complex implementation will be redone when we
have a pending extension to glyph nodes in the engine done.

Thanks Hans! Indeed, it was a fix, but there are still problems I find
in further testing, see attachment for this code:
\definefont[amiri][file:UthmanTN1Ver10.ttf*arabic at 17 pt]
\define[1]\Arab{\setupalign[r2l]\amiri#1}
\starttext
\Arab{
لرَّحْمَـٰنِ
}
\stoptext
In context the two signs are set one upon the other ("sukun" and
"fatha"), see the second attachment (word) for the correct setting. But
now this has nothing todo with ligatures, deactivating them does not
help now.

ok, another attempt uploaded (i figured out that when implementing
nested ligatures - needed elsewhere - a pointer got messed up so maybe
it's ok now (interesting is that it has always worked ok in the past so
it must have gone unnoticed)

Hmm, see in the attachment the output of MS-Word, with activated
ligatures. So it has to do anything with ConText, or not? Or maybe this
font uses in some way properties of Word in handling fonts?

i don't know what word does, but it probably uses the volt machinery.
... maybe Khaled or Idris knows
given that context can deal with more complex fonts i doubt if it's a
context issue (hard to track down as the tracer doesn't indicate any
mark position on that ligature)

If the font has OT layout tables Word will just use them, no tricks (as
far as glyph positioning is concerned). The font is fine with other
OpenType engines as well, e.g. HarfBuzz, so it is probably a ConTeXt
issue.

Khaled

Thanks Khaled, now it works, at least to some degree. I have still
problems, which I dont have with MS Word, see this example:
\definefont[amiri][file:UthmanTN1Ver10.ttf*arabic at 17 pt]
\define[1]\Arab{\setupalign[r2l]\amiri#1}
\starttext
\Arab{
نَسْتَعِينُ وَلَا الضَّالِّينَ
}
\stoptext
The vocalisations are set wrong, see attachment. Specially with a final
"nuun" there are problems. It is not a problem of the font, because in
Word they are set correctly. Does this come from the extensions ConTeXt
do not support, or is there an easy way to fix?
Or asked more generally, if fixing is not possible: Do you know any
font, which can correct handled by context, and is capable of
typesetting quran?
Thanks.

[-- Attachment #1.1: Type: text/plain, Size: 1382 bytes --]
Hoping to annoy not everybody here with my arabic-font-questions.
I have found I nice free arabic ttf-font, you can download it here:
http://fonts.qurancomplex.gov.sa/wp-content/uploads/2012/06/UthmanTN1-Ver10.zip.
One of its types is: "kfgqpcuthmantahanaskhregular"
If I type in the cmd
C:\Users\Hussein>mtxrun --script font --list --all --pattern=*kf*
I get (together with some other lines/fonts):
kfgqpcuthmantahanaskhregular kfgqpcuthmantahanaskh
c:/windows/fonts/UthmanTN1 Ver10.otf
So everything should be ok. But now the following failes:
\definefont[amiri][name:kfgqpcuthmantahanaskhregular*arabic at 17 pt]
\define[1]\Arab{\setupalign[r2l]\amiri#1}
\starttext
\Arab{
بِسْمِ للهِ الرَّحْمَـٰنِ الرَّحِيمِ
}
\stoptext
It compiles, but the output is destroyed, the letters have distances
between them. See attached pdf. (In other programms, e.g. MS Word that
does not happen, and the font is set correctly.)
Apart from this mistake, the font is perfect set by context, even the
"Allah" and its "Kassra" has a nice distance (see the other thread).
Indeed, if this distace-between-letters problem could be solved, I am
happy with arabic in context, this font would be enough, and all other
threads of mine could be closed (as far as I am concerned :))
Thanks for your help!
