Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)
ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
The Java Plug-in and Internet Explorer 8 (version 8.0.6001.18702) fails to load Applets from a server with an IDNA (punycode) domain.
A ClassNotFoundException caused by an UnknownHostException is thrown when the Plug-in tries to load the Applet.
The HostUnknownException shows that the Plug-in tries to use the hostname in unicode form and not in punycode form. In unicode form, the hostname is not a valid hostname.

---------- BEGIN SOURCE ----------
Any applet should do, I used the one from the tutorial: http://java.sun.com/docs/books/tutorial/deployment/applet/examples/applet_HelloWorld/src/HelloWorld.java
I used the following HTML but have also tried variants using the object tag and JNLP without success.
