Frankly, I'm quite on the side of the browsers that don't support this mess: the fuss over internationalized domain names (why are domains containing national special characters called "international" anyway?) is a complete scam, especially the way it was implemented. It's such nonsense, you couldn't get worse. For example, the limitation to only a restricted number of characters - no ampersand! Or this stupid idea that the browser resolves it and therefore this garbage only works on the web, but not in email (or any other programs that do name resolution). Or the brute-force method how the whole thing was rammed through in some registries. And so on, and so forth. None of this pile of junk is really worth going through all this trouble for ...
