For your font to support Arabic you need to add OpenType layout features (e.g. init, medi, fina, isol, ccmp, liga, calt, curs, mark, mkmk, etc.).

You need to get familiar with anchors, as those are important for positioning.

Also ensure your font contains these characters:
$25CC;dottedcircle;dotted circle
$200C;zwnj;zero width non-joiner
$200E;lefttorightmark;left to right mark
$200F;righttoleftmark;right to left mark
