[I18n-sig] Binary data b"strings" (Pre-PEP: Proposed Python Character Model)

That raises the question of mutability... instances of the array type are
mutable. On every occasion that I have needed a mutable string type, it has
been when the string was holding binary data.

Do we want b"strings" to be mutable?

Do we want b"strings" to be the same as the array type? (if not now, maybe
at the same time we unify plain "strings" and u"strings")
