+/**
+ * Encode/decode Internationalized Domain Names.
+ *
+ * The class allows 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.
