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)

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

ligature building, compare for instance this:
\starttext
\def\sample{نَسْتَعِينُ وَلَا الضَّالِّينَ}
\def\sample{نَسْتَعِينُ}
\def\sample{\Uchar0643\Uchar0644\Uchar0651\Uchar0627\Uchar064E}
\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.

[NTG-context] Installing an arabic font
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\Husseinmtxrun --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!

TrueType outlines and those usually have .ttf extension (though the
spec says they can have .otf extension, ConTeXt does not handle this
right now).
Regards,
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.
