I'm wondering about offering distinct "unit" (e.g. byte) and "character" types in the charset_traits class, and providing separate unit_iterator and character_iterator types and operations. Or maybe the character_iterators are best provided by some sort of "adapter" layer?
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.
