IDN FAQ : Basics

What is an IDN?

IDN stands for Internationalized Domain Name. An IDN domain name can be written in various native languages of many countries around the world. The Punycode system converts UTF-8 encoded characters into standard ASCII code domain names that are compatible with the current internet infrastructure.

What is Punycode?

Punycode is a key component of the IDN system, which allows UTF-8 foreign language characters to be converted to the standard ASCII script required for current internet traffic. Punycode domain names always start with the 'xn--' prefix, followed by the encoded character text.

To convert your native script UTF-8 text to Punycode, you can use the IDNFAQ Conversion Tool link below.
