You can use letters (a-z), numbers (0-9) and dashes/hyphens (–) in your domain name.Spaces are not allowed and the domain can’t begin or end with a dash.
Some country-level domains can also be registered as internationalized domain name. An internationalized domain name (IDN) is an Internet domain name that contains at least one label that is displayed in software applications in a language-specific script or alphabet, such as Arabic, Chinese, Russian, Tamil or the Latin alphabet-based characters with diacritics, such as French. These writing systems are encoded by computers in multi-byte Unicode. Internationalized domain names are stored in the Domain Name System as ASCII strings using Punycode transcription.
As some applications do not support internationalized domain names we not recommend to use them as your only one domain name.
