  Apple makes use of Unicode compound characters too extensively, which
doesn't go well with .ucm, not to mention *.enc

encengine can convert UTF-8 sequences for sequences of
characters - but .ucm would need tweaking to allow
multiple <UNNNN>:

<UNNNN><UMMMM> \xYYYY

  I have recently found this undocumented feature but dared not use it.
  I think it looks better if it were written as

<UNNNN+UMMMM> \xYY\xYY ....

it won't take much effort to fix it. I think I can work it out myself. Should we feed this back to IBM?

We would have to be "sure" that Unicode was normalized as well.

Right. This is rather a tough part but Apple is one of the loudest advocate of Unicode so I *think* their map is correct.
