Could you debug a bit why the Could not generate 64x64 font icon error is being generated?
This may happens because the Arabic/Urdu text is RTL direction and cairo doesn't support RTL text. You need to use Cairo integration in Harfbuzz and FriBiDi to get the direction of the text.
You need to use Cairo integration in Harfbuzz and FriBiDi
Patches very welcome for that; I have no idea how that would work.
