Nope.  You can almost certainly give your user a better error message if 
you validate the input yourself.

For that matter, a well-designed application will not even make it 
possible to enter anything but ASCII in an input field (whatever) for a 
domain name.  Basic rule of usability: making user mistakes impossible is 
better than catching them after the fact.

No, because that input is highly application-specific.
