Java - accent node name InetSocketAddress

I had a problem establishing a connection to the server with some accents (é è ô ...) in the host name.

For instance:

String oUrl = "www.hôtel.fr";   
System.out.println(oUrl);
InetSocketAddress isa = new InetSocketAddress(oUrl.toString(), 80);
System.out.println(isa.isUnresolved());

ISA is never allowed. He works at www.google.fr.

I tried to execute the URLEncode host (URLEncoder encoded in UTF-8, so the host name is www.h% C3% B4tel.fr) with no result.

Does anyone have any clues? I did not find anything on the Internet.

Thanks and sorry for my english.

In domain names, umlauts, accents, etc. must be converted using punycode. In your example, it will be http://www.xn--htel-vqa.fr/. Without testing, the IDN class can help.
