Please correct me if I'm wrong, but if Apple and Android make a nastaliq font part of the directory of fonts that go into their devices from the get go, there wouldn't be a problem.

Such fonts have already been designed. The issue now is to find Android and iOS developers who can make them default in the operating systems.

When I talked to Microsoft they said that on the smaller devices every last bit of memory was precious so they didn't want to stick extra megabytes or however big a font is. I think that Apple's cheapening out is worse than Android's, because at least Android offers the entire Urdu alphabet (though in naskh). Apple doesn't even offer the Urdu alphabet, requiring Urdu users to have to make do with 12 less letters.

I don't think it is just a matter of adding a font, with 12 additional letter for urdu. The actual layout algorithm has to change (how characters are laid out, their size, how beginning of one connects to ending of another, etc.).
