/**
* Encode/decode Internationalized Domain Names.
*
* The class allows one to convert internationalized domain names
* (see RFC 3490 for details) as they can be used with various registries worldwide
* to be translated between their original (localized) form and their encoded form
* as it will be used in the DNS (Domain Name System).
*
* The class provides two public methods, encode() and decode(), which do exactly
* what you would expect them to do. You are allowed to use complete domain names,
* simple strings and complete email addresses as well. That means, that you might
* use any of the following notations:
*
* - www.n<>rgler.com
* - xn--nrgler-wxa
* - xn--brse-5qa.xn--knrz-1ra.info
*
* Unicode input might be given as either UTF-8 string, UCS-4 string or UCS-4
* array. Unicode output is available in the same formats.
* You can select your preferred format via {@link set_paramter()}.
*
* ACE input and output is always expected to be ASCII.
