-Introduction
-------------
-
-The class idna_convert allows to convert internationalized domain names
-(see RFC 3490, 3491, 3492 and 3454 for detials) 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.nörgler.com
-- xn--nrgler-wxa
-- xn--brse-5qa.xn--knrz-1ra.info
-
-Errors, incorrectly encoded or invalid strings will lead to either a FALSE
-response (when in strict mode) or to only partially converted strings.
-You can query the occured error by calling the method get_last_error().
-
-Unicode strings are expected to be either UTF-8 strings, UCS-4 strings or UCS-4
-arrays. The default format is UTF-8. For setting different encodings, you can
-call the method setParams() - please see the inline documentation for details.
-ACE strings (the Punycode form) are always 7bit ASCII strings.
-
-ATTENTION: We no longer supply the PHP5 version of the class. It is not
-necessary for achieving a successfull conversion, since the supplied PHP code is
-compatible with both PHP4 and PHP5. We expect to see no compatibility issues
-with the upcoming PHP6, too.
-

-Files
------
-
-idna_convert.class.php - The actual class
-idna_convert.create.npdata.php - Useful for (re)creating the NPData file
-npdata.ser - Serialized data for NamePrep
-example.php - An example web page for converting
-ReadMe.txt - This file
-LICENCE - The LGPL licence file
-
-The class is contained in idna_convert.class.php.
-MAKE SURE to copy the npdata.ser file into the same folder as the class file
-itself!
-
-
-Examples
---------
-
-1. Say we wish to encode the domain name nörgler.com:
-
-// Include the class
-include_once('idna_convert.class.php');
-// Instantiate it *
-$IDN = new idna_convert();
-// The input string, if input is not UTF-8 or UCS-4, it must be converted before
-$input = utf8_encode('nörgler.com');
-// Encode it to its punycode presentation
-$output = $IDN->encode($input);
-// Output, what we got now
-echo $output; // This will read: xn--nrgler-wxa.com
-
-
-2. We received an email from a punycoded domain and are willing to learn, how
- the domain name reads originally
-
-// Include the class
-include_once('idna_convert.class.php');
-// Instantiate it (depending on the version you are using) with
-$IDN = new idna_convert();
-// The input string
-$input = 'andre@xn--brse-5qa.xn--knrz-1ra.info';
-// Encode it to its punycode presentation
-$output = $IDN->decode($input);
-// Output, what we got now, if output should be in a format different to UTF-8
-// or UCS-4, you will have to convert it before outputting it
-echo utf8_decode($output); // This will read: andre@börse.knörz.info
-
-
-3. The input is read from a UCS-4 coded file and encoded line by line. By
- appending the optional second parameter we tell enode() about the input
- format to be used
-
-// Include the class
-include_once('idna_convert.class.php');
-// Instantiate it
-$IDN = new dinca_convert();
-// Iterate through the input file line by line
-foreach (file('ucs4-domains.txt') as $line) {
- echo $IDN->encode(trim($line), 'ucs4_string');
- echo "\n";

-NPData
-------
-
-Should you need to recreate the npdata.ser file, which holds all necessary translation
-tables in a serialized format, you can run the file idna_convert.create.npdata.php, which
-creates the file for you and stores it in the same folder, where it is placed.
-Should you need to do changes to the tables you can do so, but beware of the consequences.
