Punycode is an encoding language primarily used to encode Unicode characters to represent them in ASCII. The main purpose of the Punycode encoding language has been for internationalized domain names (IDN), however in practice very few top-level domains adopted the usage. IDN installation in the DNS root zone was done in 2010 but Punycode encoding was not automatically activated in browsers until 2018.
