Domain names + Unicode = Punycode

I Saw.

I saw a unicode symbol of a white star enclosed in a black circle the other day, in a domain name.  So last night I set out to see unicode characters in a domain name for myself.  I started at my favorite Registrar name.com.  Some of the country code domains they sell allow unicode characters.

I Bought.

So I chose ⤷.ws  the .ws was the cheapest option coming in at $14.5o, and as you no doubt know .ws is the TLD for Government of Samoa.  First thing that I notice while setting up my DNS was that domain showed up as “xn--2ri.ws”.  What is that all about?  Well, although I really kinda hoped that the internet had progressed to the point where we can all handle unicode, it hasn’t.  So in order to implement Internationalized Domain Names or IDNs, we still use Ascii.  How?

I Wikipedia’d.

Punycode is a means to represent a larger character set (unicode) with a smaller more restrictive character set (ascii).  Do to some security concerns around spoofing urls many browser will show the punycode that represents the unicode domain in the address bar, although some do this selectively such as safari.  Many countries are retrictive on the allowed characters, usually ascii + their countries language, but there are some that have just allowed them all (thanks Samoa).  So my new url shorten is in place, http://⤷.ws
