That's what I'm saying, they'll choose the 1st of your options :)  I think the 2nd is a limited case, and probably only chosen because a lack of reasonable alternatives.

Shawn, if I'm doing business internationally and my addresses
are in a script that that my business partners might consider
obscure, I am almost certain to either

        * make sure I have alternative addresses (both email and
        relevant URLs) in ASCII characters    or

        * make sure I show A-labels

on business cards, letterhead, etc.   The latter constitutes
"handy" in my vocabulary.    If someone asked my advice, I would
probably recommend the first.   But it is very clear from many
conversations that some people will pick the second.

If they are "sales guys and teachers and kids and parents" whose
relationships and correspondents include people who don't
natively use the same script, they will have the problem
described above and will have to solve it somehow.
