The problem that I thought we may face is internationalized mailboxes
and domain names *are still ASCII* which encodes Unicode.
OK, I looked it up, and I was almost certainly wrong. The relevant
RFCs are actually 6531 (SMTPUTF8 extension), 5890 (IDNA), and 3492
(Punycode). IDNA allows "U-labels" (UTF-8), which we can gracefully
extend to, and "A-labels" (encoded using Punycode, which uses the
ASCII repertoire). AFAICT (haven't really looked carefully), Punycode
uses only letters, digits, and the hyphen ("-").
So I withdraw the comment.
Thanks for your work on this, Mark!
