For the  tag's   attribute, non-ASCII characters are URL-encoded as follows: a period  followed by a capital hexadecimal code. For example,  produces.

www.example.org is not a real website, but it has been reserved to use in software documentation. If you translate the word example and try to go to that web address then you might get a message that it doesn't exist. But somebody may have created a commercial web page for that address, such as www.Beispiel.org, using the German word for example. It is therefore recommended that you do not translate http://www.example.org at all. If you do wish to translate it you should first check where the translated link takes you.
