Frank - I understand your concerns. But one way of looking at what we
need is some tagging format possibly used in ACAP and IMAP, which
MUST not leak to other places. And what you probably worry about
is the C1 area in terms of octets (which is already gone with UTF-8)
and not the C1 character space in Unicode, which turns up as two bytes
in UTF-8.
