A non-delivery-notification (MIME multipart/report content type
RFC3462) consists of (up to) three parts:
1. Required initial free-form body part, this can use UTF-8
without any need for EAI.
2. Required message/delivery-status machine readable part,
this requires EAI for non-ASCII content. (RFC3464).
3. Optional returned message or message headers. If
the returned message has UTF-8 headers, it may need
to encapsulated as an EAI message/global
My interpretation of the question was that you wanted UTF-8 in the
"part 1", body, in which case *in principle* you could have raw
UTF-8 there, and a "charset=utf-8" attribute for the enclosing MIME
part, provided that the code that generates bounces (in this case
in Exim) allows you configure the charset and associated content.

Well, it still depends on which part of the NDN you want in (e.g.)
Russian.
