I don't get the 'locl' feature to work with Arabic script, the attached sample should give diagonal dots not rounded ones (it does if processed with luatex). 'locl' feature works just fine with Latin script in other fonts.
Is this a XeTeX bug, feature or even a known limitation? The font might be buggy off course (though it works with other OpenType engines as well), but I want to be sure before putting much effort debugging the font. Regards, Khaled
