AFAIK, this has changed with MIME. RFC 822 restricts email messages
to 7 bits (ASCII), but MIME allows different charecter sets, like
UTF8. What is still a possibility is that such a message will get
mangled on its way by an MTA that assumes all data is ASCII, but I
don't remember seeing anything like that happen.
BTW, RFC 2045 specifies a way to pass non-ASCII messages through
MTA's that assume all-ASCII world: the Content-Transfer-Encoding
header.

Looks like you confuse HTML and MIME, which are two distinct things
that have moreless nothing in common.
For example, this message is a MIME message (as opposed to an RFC
822 message, yet it doesn't contain any HTML).
If we restrict this to MIME: I routinely see messages from Outlook
and its brethren claiming they're ISO-8859-2, but containing
characters from outer space.
