In article <3eea2f77-8aea-4f49-80f3-d96b639c378a@isode.com> you write:

Oops.

That seems the smallest adequate fix.  In general EAI allows UTF-8 in
fields that humans look at, but not ones just for computers like
message-IDs.  The alternative would be to leave the old text and add a
note that says in the common case that the identifier is a domain
name, IDNs are represented as A-labels.
