Internationalized Domain Names

How IDNs work

Technically, the “special” characters are encoded using a conversion table. This is why an IDN domain name will begin with the four characters xn––. For example: bébé.eu becomes xn-–bb-bjab.eu. (This is also why you can't otherwise register domain names with hyphens in the third and fourth position.)

The IDN System is specified by RFC standards 3490, 3491 and 3492.

Note that IDN do not work with email addresses.
