Traditional Arabic is a uniscribe-compliant font, but not a fully opentype font. Uniscribe also supports older, pre-unicode protocols. In other words, TraditionalArabic is platform-dependent. So unless M$ has updated it in a recent OS, it will not work in ConTeXt MkIV. It did (all its fonts actually), it now uses GPOS for mark placement. Since XeTeX uses the local libraries, then mkii/xetex on windows might work. XeTeX does not use any system libraries for its OpenType layout, in the past is was using ICU LayoutEngine and now it is using HarfBuzz, in all platforms (i.e. a third party library, but not a system one). However, HarfBuzz has heuristics to place marks based on glyph bounding boxes in the case of GPOS absence (a bit similar to TeX's \accent but knows which marks goes above or below or off the center).

Yes, again, kassra is set too low, in both fonts. But with
traditionalarabic it is worse than with arabtype. What could be a way to
fix this?
fix the font

my guess is that the bottom mark is not dealt with in the font (as
arabtype also has it too low i.e. there is no mark applied) .. is this
valid arabic input?

Re: [NTG-context] Arabic typesetting, one more
Any ideas, where this bug comes from? Seems weird, that it affects only one sinlg lettercombination, in other programms this do not occur. Thanks.
