  Yes there is SMTPUTF8, which is a special protocol.
  The /global MIME thing i personally have _never_ seen in practice.
  I have downloaded the RFC on 2012-07-23.

  I cannot comment on that.  I am pretty sure i have never seen
  /global yet.  Ie an archive search here reveals only three mails
  where i mention them in the text; the last is from a thread from
  nmh-workers@nongnu.org from July this year, and let me shamelessly
  quote Ken Hornstein who said on 2023-07-23

   The message/global MIME type (a RFC822 message but with UTF-8
   everywhere) has a suggested file extension of ".u8msg", which
   I have never personally seen "in the wild" anywhere.  ¯\_(ツ)_/¯

You need, to the best of my understanding, send messages as the
MIME type message/global in order to send UTF-8 internationalized
email.
