Unicode URL - ☃.net
xn--n3h.net
xn--n3h.net
Unfortunately, it doesn't work well on all browsers/DNS servers, so it's not very practical.
I raced home to find out if ♥.com was taken. I 1st tried checking it by just typing alt+3 .com in chrome's address bar, only to find out that you can't. Chrome just won't accept it. So I tried in IE and noticed that while it "resolved" out to xn--g6h.com but there was no site. Excellent I thought and quickly tried to register it only to find that I'd been beaten by about 9 years. As I checked for other available single unicode domains I found that most of them had been snapped up around 2003.
i♥you.com is for sale.
No real point to this story except that I was once again reminded that as geeky and "internet hip" as I like to think I am, I find I'm continuously 5-10 years behind the real smart people.
(for those who don't get it: the L of paypal is not an L)
I never came around to using it, so if a fellow HNer is interested in the domain, drop me a line (email in my profile).

However, CJK domains are a potential goldmine if you factor in:
1. Most internet ready devices in Asia have Unicode input (language-wise). For example, they can easily type 日本.com (Japan).
2. China's internet users count has surpassed 500M.
A brief lookup revealed that the most common 1-2 character domain names have already been picked up.
