I think providing the code point iterators in a adapter layer is better.
The reason is that iterating over code points is just one of several
higher-level-than-byte- iterations that might be useful.  In particular,
it seems that for many string manipulation tasks, even iterating over
code points is not sufficient to handle international text; rather, it
may be necessary to iterate over grapheme clusters.
