I'm a little less sanguine about that. It depends on the software, and on
how (and whether) local SW industries develop. Suppose a Uighur speaker is
using Arabic software, or that a software vendor Uighurizes an Arabic
package and decides its good enough to allow waw+damma as U+06C7, following
the same logic that says its up to higher levels to decipher Slovak 'ch'.
If the world of Arabiform w-languages were as software-rich as the world of
Latinate w-languages, I think we would see lots of different ways of using
Unicode to encode the same thing. No matter how the data is entered, we
still have the problem of how to interpret it. Since Unicode doesn't want
to get involved in language-specific encodings (at least not outside of a
core set of languages), what is really needed is another standard (or a set
of them; at least one per language) for which Unicode is a resource, which
would indicate how various Unicode strings are to be interpreted in various

Right, that makes sense. But Unicode is quite inconsistent in this area -
witness the Slovak 'ch' brouhaha. Similar considerations arise in various
aspirated consonants in Arabiform w-languages. I believe in Urdu spelling
such "letters" as consonant+soft h is acceptable, but in other languages it
looks to me like the consonant+soft h should be treated as a distinct single
character - like 'ch' in Slovak.

I think compositional mappings would do it. Then the semantics would be
there, in the data. Of course, it might be language specific, since such
mappings may not apply outside of the Arabic w-language. But extra stuff in
Unicode seems like a better idea than not enough stuff.
