问题
What is the browser support for having images, links, scripts... containing unicode characters in the domain name?
For example does IE5+, chrome, firefox, opera, safari, and mobile browsers (Dolfin, Blackberry Webkit, MicroB, Phantom, IEMobile...) all support the following statement?
<script src=☺.com/s.js></script>
Just attempting to understand the portability of the above statement.

Wikipedia's Internationalized domain name article says this:
Mozilla 1.4, Netscape 7.1, Opera 7.11 were among the first applications to support IDNA. A browser plugin is available for Internet Explorer 6 to provide IDN support. Internet Explorer 7.0[13][14] and Windows Vista's URL APIs provide native support for IDN.[15]
Considering the age of those browsers, I'd guess that any newer browser, including any WebKit-based browser, supports IDNs.
