A U-label is an IDN domain name with special characters, such as belgië.be
An A-label is the ASCII version of a U-label; in other words: an A-label uses ASCII characters only (A-Z, 0-9 and/or ‘-’) to display the domain name. This conversion is carried out automatically by the DNS Belgium registration system. This conversion is required to enable your browser to surf to the correct page. For example, the U-label belgië.be is displayed as xn--belgi-rsa.be when converted to an A-label.
