Despite your ingenious special pleading, I don't see how this can mean
anything except that chars must be 16-bit unsigned integers.

Character literals are crocky anyhow. IMHO modern programming languages
should not have a Character type, but deal only in Strings.

I doubt it very much. 17 planes is waaaay more than sufficient.
