No.  I just thought about the possibility that some primitive might
convert unibyte characters such as \200 into multibyte eight-bit-*
characters (to provide the behavior users expect).  If such cases do
exist, they might conflict with this change.

Yes, but I remember that some of the primitives silently convert
between unibyte and multibyte because users expect that.  Isn't that
the case?
