Indeed -- but at the moment, we're letting people continue to
use strings this way, since they already do it.

I would like it to be only the latter, as Fred, i, and others
have previously suggested, and as corresponds to your ASCII
proposal for treatment of 8-bit strings.
But doesn't the current locale-dependent behaviour of upper()
etc. mean that strings are getting interpreted in the first way?

I'm afraid i have to agree with this, because i don't see any
other option that lets us escape from any of these four ways
of using strings...
