They write: A native Java and C# port is included.

Does it mean the Java lib just calls C? Or is
it a pure Java implementation? I am thinking
about bundling the jar with an applet, so when
it uses some native component then it would be
problematic.

There is indeed some sun lib which has for
example Punycode:

	package sun.net.idn;
	public final class Punycode;

But using such libraries does not work,
because for example an Oracle applet does bar
the package sun.* from use in an applet. One will
get an exception. Which makes sense, since different
applet provides might have different internal
libraries.

I guess sun.net.idn is old, judging from the change log:
http://www.docjar.com/html/api/sun/net/idn/Punycode.java.html

Maybe there is a com.ibm.icu jar?
