So, it seems in the end we have come to agree on all the facts,
and the only disagreement is as to what conclusion follows from
Arabic/Persian Heh has four shapes, and Kurdish H has two shapes
(namely two from the four used by Heh), and Uyghur H has two shapes
(namely two from the four used by Heh), and Urdu has one or two shapes
(different from the four used by its `small' He).
If one is forced to use for Uyghur H a code point that already exists,
I can see that U+06BE, introduced for Urdu, is the best choice.
But that is a hack. It is wrong, but the best one can do
with today's standard.
The reason that I call it wrong is that Uyghur shaping is well-defined,
while Urdu in the most common font shape uses only a single form,
and manuscripts and fonts that use two shapes vary in usage.
The reasoning used to establish that Uyghur H can use the Urdu
U+06BE since the latter is ill-defined anyway and can be used
in the Uyghur way, can also be used to establish that Kurdish H
can use the Urdu U+06BE. But Uyghur and Kurdish treatments seem
to be well-defined and distinct.
