Module: ForgivingURI::IDNA

Defined in:
lib/rfeedparser/forgiving_uri.rb

Overview

This module handles internationalized domain names. When Ruby has an implementation of nameprep, stringprep, punycode, etc, this module should contain an actual implementation of IDNA instead of returning nil if libidn can’t be used.
