Setup an IDN in WHM/CPanel

I recently ran across a question where the user wanted to setup an IDN (Internationalized Domain Name) in WHM/Cpanel. For those wondering, an IDN is a domain name that uses non-ASCII characters, such as ñ, ü, ý, etc. I learned that the process to setup such a domain in WHM/Cpanel is quite simple.

To setup the domain in WHM, you first need to convert the IDN domain name to Punycode. For example the non-ASCII domain name “xn--fsher-kva.com” converts to the punycode version, “xn--fsher-kva.com”. Once you have the punycode version of the domain, you’re set to go. Just make sure account username does not use punycode or any non-ACII characters. Just use plain ASCII characters for usernames.

For example: If the domain name to setup was füsher.com. I’d use this in WHM:

domain name: xn--fsher-kva.com
username: fusher

Here’s a handy punycode converter.
