Punycode (the way Unicode maps to DNS names) is pretty clever. Characters for a given language are close together, so Punycode optimizes for encoding characters close together. https://en.wikipedia.org/wiki/Punycode https://en.wikipedia.org/wiki/Punycode Here's an example from the RFC: https://tools.ietf.org/html/rfc3492#section-7.1 https://tools.ietf.org/html/rfc3492#section-7.1 Unicode: 他们为什么不说中文 DNS: xn--ihqwcrb4cv8a8dqg056pqjye utf8 base64: 5LuW5Lus5Li65LuA5LmI5LiN6K+05Lit5paH Let's see if HN will link these: http://.ws http://.ws -> http://xn--ls8h.ws/ http://xn--ls8h.ws/ edit: Nope, it strips (!) emoji from comments.
