About IDN & Punycode
Internationalized Domain Names (IDN)

IDN allows domain names to contain Unicode characters from various languages and scripts, making the internet more accessible to non-English speakers worldwide.

Punycode Encoding

Punycode is an ASCII-compatible encoding used to represent Unicode characters in domain names. It uses the "xn--" prefix followed by encoded characters.

Examples
café.com → xn--caf-dma.com
münchen.de → xn--mnchen-3ya.de
пример.рф → xn--e1afmkfd.xn--p1ai
