E.g. Chrome only shows Unicode if they have indication (prolly locale)
that the end-user will understand it and will use ACE otherwise. I do
not want that kind of logic to leak through developer-exposed APIs.
That's madness.

See http://wiki.whatwg.org/wiki/URL#UI for links to more details.

If we can define "until we can't" I would be okay with that. Otherwise
it seems safer to always use punycode and delegate the problem.
