Punycode & IMA/EAI

[James Seng]

I think (b) is most likely something we put in the specification as an
"error checking" so we could warn the users but would not stop it from
moving forward.

afterall, a non-IDN awared app will behave as (a) .. and it is for
that specific behavior, ie backward compatibility that we have
IDNA/punycode solution today.

The cases where punycode will solve problems isn't going to touch the usability, and as a sales rep or whatever I cannot use a Unicode name if it isn't usable to the people reading my card.

This isn't a problem if the Unicode is "normalized".  It could be a problem if the Unicode is in a case mapped form or other form that might not make the conversion straightforward.
