It occurs to me that this is probably not a DKIM topic at all.  I don't mean 
that it isn't relevant to DKIM, but rather that it is not *specific* to DKIM.

EAI is a long-standing problem and canonicalization of email text is a 
long-standing issue.  I suspect that your focus is appropriate to a venue with 
that mix of interest, rather than DKIM, per se.

Let me suggest this more strongly:  These arenas of internationalization and 
canonicalization have proved exceptionally difficult and the sort of thing you 
are attempting to pursue *should* be of benefit -- and therefore interest -- to 
the larger email text-handling community.

That said, I'm not sure what venue to suggest, and I don't want to guess, lest 
it confuse things further.
