I'm extremely in favor of internationalizing the web as much as possible.<p>But this is a mistake. Just like air traffic control, there needs to be some minimal set of language standards web administrators should have. English had become the de facto standard, and while not optimal (maybe), at least it was working.<p>Do you know how many international characters look alike but aren't? How difficult it's going to be to debug domain names by sight? You'd be better going back to hex.<p>Maybe I'm not up to speed on the tooling, but I think this is going to be a mess in the long run.
