Unicode is developed based on the standard of the Universal Character Set and also in the form of books (the Unicode standard, currently fifth edition published by Addison-Wesley professional, ISBN-10: 0321480910) external publication.

The latest Unicode version in July 2006 is 5.0. Unicode 4.1.0 was launched in March 31, 2005. In addition, the version 5.0 Beta was launched in December 12, 2005 and the version 5.2 (UNICODE standard) was officially launched in October 1, 2009 for comments by members.
Currently, the Unicode Standard Version 6.1 has been released (January 1, January 31, 2012 ). On the Unicode Alliance website, you can view the complete 6.1 core specifications.
Unicode defines a character set that is large enough to represent all human readable characters.
