Punycode Cocoa

v1.1 (2015) by Nate Weaver (Wevah) http://derailer.org/ https://github.com/Wevah/Punycode-Cocoa

A simple punycode/IDNA category on NSString, based on code and documentation from RFC 3492 and RFC 3490.

Use this to convert internationalized domain names (IDN) between Unicode and ASCII.

To use in your own projects, all you need is NSStringPunycodeAdditions.h/m. This project includes a sample testing app.
