The set of characters admitted in the requests for .it registration has been extended: the IDN (Internationalized Domain Names) includes the 24 official languages of the European Union. With this new feature, the characters admitted for the registration of an .it domain are made up of all the characters belonging to the charsets (editor’s note: codes) Latin-1 Supplement, Latin Extended-A, Latin Extended-B, Greek, Greek Extended and Cyrillic. Not accepted are domain names that contain characters belonging to different charsets (Latin, Greek, Cyrillic), excluding of course the suffix “.it” and names and domains belonging to the geographic tree map.
