Now we can register a domain name with all kind of Cyrillic or Greek characters, such as "Удача.eu"(*) or "Καλήτύχη.eu"(*). This is good news!
I frankly think it is a very good
However, I doubt that such use of the ".eu" TLD will also help the global audience to reach these websites.
One issue is as obvious as important: keyboards. Not everybody will be able to use the international characters unless clearly displayed on a keyboard.
I suppose that Internet browsers will have to start working pretty soon at some version of an integrated virtual keyboard, possibly with translation features. It's not a bad idea to drop a request to Mozilla...
(*) Both domain names mean "Good Luck."
Please do not squat this URLs :)
