    I have to correct this because it may seriously cast doubts about the
    ability of Internet email to send Unicode files.

    All these extensions are referenced in the same RFC, 2821, which is
    the authoritative one about SMTP. I do not know any mainstream SMTP
    server which does not implement them.

    The most important for us is 8BITMIME:

       Eight-bit message content transmission MAY be requested of the server
       by a client using extended SMTP facilities, notably the "8BITMIME"
       extension [20]. 8BITMIME SHOULD be supported by SMTP servers.

    This is absolutely wrong. sendmail, Postfix and qmail allow 8-bits
    transport for a *very* long time.

    I send Latin-1 (ISO 8859-1) emails for more than ten years (and
    without using quoted-printable or other similar hacks) to
    French-speaking people in various parts of the world and I'm still
    waiting for an actual problem.
