I don't understand this. Raw 8-bit isn't allowed, but base64 or qp
can be used (including the identification of the encoding).
You may be able to put UTF-7 into email header fields, even at
some positions where you can't put RFC 2047 stuff, but no
MUA (or MTA, for that matter) will recognize it and use the actual
characters, which means it's pretty useless.
