Can I just register the domain xn-Â-Âd1aiy.Âcom at Godaddy to have users visit дир.com (a domain with Cyrillic characters) or do I have to use a special registrar for domains with Cyrillic characters?
I don't think that if you register domain with cyrilic the sites will be popular, because it is hard to enter such address for western countries into their browsers )))
I suppose that would be popular in some regions only and that will not be popular worldwide. So better to ask for the opinion in the places where people are interested.
