People who speak (read / write) languages, that do not use Roman character sets, need to publish in their native language - and the Internet now supports that need . Some registrars will register domains which use non Roman character sets, in the URL. Not all Internet services will accept non Roman characters, however. My favourite online DNS diagnostic services, DigWebInterface , and intoDNS , and Rex Swain's HTTP Viewer , only use ASCII. One cannot use non ASCII ("non Roman") characters, with either service.
