Re: Joining Arabic Letters

This is smart... provided that fonts also map the ZWJ (not all Arabic
fonts map it, they often map only ZWNJ to disable joinings, assuming
that there's no reason to force the joining in normal texts; some
Arabic fonts do not even map ZWNJ as well).

Some Arabic fonts do not even map the joining types internally but
depend on the engine to find the contextual forms by trying with the
compatibility characters (so they are not suitable for anything else
than basic Arabic).
