Why do we want this interface at all, aside from backward
compatibility with legacy Mule?  With Unicode inside, a
`get-char-components' function must be set-valued or nondeterministic
(it depends on some global precedence list), and

    (eq (list cs o1 o2)
        (get-char-components (make-char-from-components cs o1 o2)))

is mostly false.  `charset-of-char' and `octet-of-char' don't make
sense as separate APIs, they must be generated together.

As far as I can see, this is not something that can be done right.
There are only different ways to do it wrong, none of which are very
attractive to me.
