Is 'opbd' feature supported? According to the spec[1] this feature is used to define what I think is equivalent to the protrusion values used for optical alignment of the glyphs. I grepped the sources and there seem no be special handling of it, I don't have fonts that use this feature (I didn't look for one) but I'm planning to use it in my fonts and thought I'd check if ConTeXt support it first.
This Typophile thread[2] might be interesting too.
If fonts are needed I can check for free fonts that implement this, or prepare a font for testing.

Indeed I need a test font in order to see how it can be implemented. If there are no fonts we should wonder what the exact spec is. Does fontforge support it?
I think fontforge supports it, I'll check existing fonts and if I found nothing I'll create one for testing; if there is no fonts using it then we are free to interpret the spec as we will, after all, using our own fonts in our own system :) Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
