Use of A-labels within header fields supporting UTF-8 is a bad idea.
Since DKIM is defined on RFC 5322 messages, and 5322 is ASCII-only, no
header fields in a compliant message can contain UTF-8. I don't know why
you keep repeating this uttetly wrong stuff, but please stop now.
Changing a reference of RFC3490 to RFC5890 already represents an incompatible
change.
Your assertion is noted.
