Hi all,

this is my MWE:
\definefontfeature [arabis]
[mode=node,language=dflt,script=arab,
init=yes,medi=yes,fina=yes,isol=yes,
liga=yes,dlig=yes,rlig=yes,clig=yes,
mark=yes,mkmk=yes,kern=yes,curs=yes]
\definefont [Ahang] [file:Ahang-Regular.otf*arabis at 18pt]
\setupalign[r2l]
\starttext
{\Ahang تَشْكِيل كَسْرَة}
\stoptext
\definefont [Ahang] [file:Ahang-Regular.otf*arabic at 18pt]
but there is an issue with widths, ill send you a patch to test
The provided "*arabic" featureset should suffice for this font. Also TEXpage is useful for this kind of MWE:
\definefont [Ahang] [file:Ahang-Regular.otf*arabic at 18pt]
\setupalign[r2l]
\startTEXpage[offset=1em]
{\Ahang تَشْكِيل كَسْرَة}
\stopTEXpage
In prehistoric ConTeXt version
2023.09.26 18:19
the diacritics look fine in both ConTeXt and unicode editor MS Notepad.
So if there is something wrong, it must be in a more recent version.
For comparison: Before applying Hans' patch, could you kindly send your pdf of the MWE that shows the error? Mine is attached.
Best wishes
Idris
