I am talking about IDNA. With IDNA, we do not add matching algorithm
to any server. Some client may try "az--" and it fails, it may try 
"bz--" with TC/SC feature-enabled preprocessing, while others only 
try "az--". I know this may look quite ugly. But, current IDN proposal 
seems premature in terms of internationalization at least from the Chinese 
people's point of view.

Allowing Unicode be used where only ASCII was used before is not enough 
for internationalization. We should prepare an enough room in which
localization can be done while complying with internationalized standards.

Yes, I totally agree.

Why are we going to hide and ignore problems even though we know they are
there ?

My conclusion is the same with yours.
