It would be limiting to have this as the *only* way of
dealing with unicode, but I don't see anything wrong with
having this available as an option for applications that
truly don't need anything more than ascii. There must be
plenty of those; the controller that runs my car engine,
for example, doesn't exchange text with the outside world
at all.

No, I think the rationale is that UTF-8 is likely to use
less memory than UTF-16 or UTF-32.
