PHP 6 and Unicode

a PHP 5.3 release was created in 2009, with many non-Unicode features back-ported from PHP 6, notably namespaces. In March 2010,
Initial hopes were that a new plan would be formed for Unicode integration, but as of 2014 none have been adopted.

During 2014 and 2015, a new major PHP version was developed, which was numbered PHP 7.
Because of major internal changes in phpng, it must receive a new major version number of PHP, rather than a minor PHP 5 release, according to PHP's release process
