Frequently asked questions
Testsigma provides a free IDN Decoder that converts the domain name with special characters (Unicode) to their actual Punycode encoding.
IDN domains work by decoding the domain name using a system called Punycode. The IDN Decode online tool converts the domain name to Punycode that you receive when you register for an IDN domain. When users enter a URL containing an IDN domain into their web browser, it converts the IDN domain into Punycode and resolves that domain.
