Can you give a concrete example along with the point where you observe
ambiguity? I believe that internationalised e-mail just uses UTF-8 on
most of the higher layers. I don't believe MUAs even need to deal with
IDN, they just use UTF-8. And WKD seems to work as interacting MUA's and
static HTTPS URLs. So I'm not quite following where the problem comes
in. You send a mail to an UTF-8 address. You receive a reply on an UTF-8
email address, and so on, and the URL for key retrieval doesn't actually
contain the domain name, so there is no problem with the domain name
there either.

HTH,

Peter.
