Most definitely.

As I said, something along these lines:

HTTP: apparently no change needed (it does work already)

SMTP: add a new extension: UTF8HEADERS; if the sending-to
      server does not declare that it can process UTF8HEADERS,
      then (among other things) look up the ASCII fall-back names
      for all IDNs in the message *headers* and use as replacements
      in the headers. As a fall-back to the fall-back, use the
      IP number "name".

SNMP, and other protocols that I'm unfamiliar with but are already
deployed (and not targeted to be more or less replaced anyway):
Some similar measures need to be done (I can't say exactly
what, since I'm not familiar with them).

                Kind regards
