See Full FAQAn IDN is a domain name that contains non-ASCII characters, such as accented letters or characters from languages like Chinese, Arabic, and Cyrillic.
Punycode is a way to encode domain names that contain Unicode characters into an ASCII format that can be used by the Domain Name System (DNS).
IDN refers to domain names that contain non-ASCII characters, while Punycode is the ASCII-compatible encoding used to represent them. For example, 'münich.de' in IDN format becomes 'xn--mnchen-3ya.de' in Punycode.
Some systems, such as domain registrars and older browsers, require Punycode for compatibility with non-ASCII domain names.
Yes, you can decode a Punycode domain back into its original IDN format.
