Frequently asked questions
What is punycode?⌄
A way to represent a domain in any script (e.g. "münchen.de") as an ASCII string (e.g. "xn--mnchen-3ya.de") that the DNS system, which originally only supported Latin characters, can understand.
When would I need this?⌄
The punycode form is needed for DNS setup, SSL certificates, or other technical work with internationalized domains (IDN), where a registrar's usual interface shows the domain in Unicode.
