Thanks Hans, that worked quite well. Not perfect independent from the 
size, as you can see in the attached image, but perfect enough for my 
case, as the sizes differ not soo much (only 1-2pt).

as 'ex' is bad font that font, you can try 'em' :

\setupbars[overbar][offset=1.2,unit=em,rulethickness=.05]

Thanks Wolfgang, but this solution is not independent from the size of 
the font, and so had to be adjust for each size again (bad for my 
project, where the font-size changes on nearly every page).

Which unit has this offset?
\setupbars[overbar][offset=3]

I tried the font-independent unit em
\setupbars[overbar][offset=3em]

but that does not work.

Adjusting overbar for a special font

["H. Özoguz"]

[-- Attachment #1: Type: text/plain, Size: 1257 bytes --]

Hello there,

I tried to overbar an arabic word, and noticed, that the bar is too low 
and overlaps the letters. While producing a minexample, I noticed that 
this might be a issue of my font, because this does not happen with 
Arial. See this minexample:

\definefont[arial][name:arial*arabic at 12pt]
\definefont[arabicuth][file:UthmanicHafs1Ver09.ttf*arabic at 12pt]

\starttext
\startalign[r2l]
\arial
كَلَّا لَا تُطِعْهُ \overbar{وَٱسْجُدْ} وَٱقْتَرِب ۩
\arabicuth
كَلَّا لَا تُطِعْهُ \overbar{وَٱسْجُدْ} وَٱقْتَرِب ۩
\stopalign
\stoptext

and compare the compiled pdf in attachment.

You can download the used font-file "UthmanicHafs1Ver09.ttf" here:

http://fonts.qurancomplex.gov.sa/download/UthmanicHafs1Ver09Font.zip

We have discussed this font here month ago, hans commented: "yes, but 
calling this a normal font is somewhat over-the-top"

So it is quite "special" - but still best available font (free or 
commercial) for typesetting the holy quran.

But setting the bar a bit higher should be easily possible, independent 
of these font-lacks, right? The solution should be independent from the 
chosen font-size.

Thanks!
Huseyin
