Thanks Ali.
It worked good. Just failed for Tatweel. I suppose, it's due to this
fact your algorithm considers surrounding characters abilities for
reshaping -having [sfim] members in structure- but it's not sufficient,
at least for your table. Old code works because it's somewhat agnostic
about character abilities and it calls half-shape anyway.
I think one solution is change Tatweel structure to something like
{0x0640, 0, 0x0640, 0x0640, 0x0640}
or change can_join(), though I've not tested it yet.
