CentralNic Unicode Library 0.0.1

The CentralNic Unicode Library provides some PHP classes for maniuplating Unicode data. These classes are general purpose but are intended for use when working with Internationalised Domain Names (IDNs).

Existing support for Unicode and multi-byte strings in PHP is not great, requiring either an extension that is not compiled into PHP by default, or one of a number of third-party libraries, most of which are not currently maintained (for example, the
I18N_UnicodeString class in PEAR was last updated in August 2004).

There is a Unicode extension under development, but it isnt public yet, and again requires a third party library to do the heavy lifting, so probably wont be enabled in a default PHP build.

Using the CentralNic Unicode Library is as simple as downloading the current release, and including the main Unicode.php file from your scripts. You then get instant access to the two Unicode_String and Unicode_Character classes.

The CentralNic Unicode Library is released under the GNU Library General Public License, version 2.0. This is not the "Lesser" GPL (version 2.1 and higher), which is more restrictive.

The use of the Library GPL means that you can use the code in your own proprietary software. While you are not obliged to pass back any changes you make to the code, we would greatly appreciate it if you did.
