Hmm.  That _does_ suck if you want to show location stuff to the user, 
though.... (though a proposed ACE-to-Unicode API would somewhat help, if 
you remember to use it).

You mean the decision as to when exactly to use the Unicode and when to 
use ACE?  In what way is it a UI decision (apart from browser URL bars 
having anti-phishing logic that falls back to ACE when they detect 
"weird" chars in the URI)?

Agreed, but that doesn't help answer the question of what authors should 
get in the DOM.

Or put another way, it seems like we should be trying to use IRIs until 
we can't for some reason, and I see no a priori reason that 
location.href can't be an IRI...
