Yes, and we can have TextIterator work on binary strings as well
(perhaps by adding TextIterator::BYTE constant).

IIRC, TextIterator is specifically designed for Unicode, letting you
iterate over codepoints, combining sequences, characters, words, etc. So
making it do all that would only make sense with intl, and even then not
really (as Stanislav points out performance-wise).
What I was suggesting was a shortcut to iterating over binary data; i.e.
byte by byte.
