First, just to be clear, we are really only discussing the representation
of domain names within the data base.  Of course, any email address contains
one of those, but we are specifically -not- discussing the representation
of the user-ID portion of any email address in the data base.

Second, it is nice that you are OK with "properly coded non-ASCII" domain
names in the data base.  So I am I.  That's not the question.  The question
is how should IDNs be -represented- within the data base.

As I have stated, it is my opinion that the only two viable options at
the present time are either (a) punycode or else (b) UTF-8.

ISO-8859-1 is not, as far as I know, a standardized or appropriate way
of encoding IDNs in any context.  If I am wrong about that, then please
do correct me an please do point me at the RFC which states otherwise.
