Andrei Zmievski has posted an encouraging note on his blog about the progress of PHP6 concerning the number of functions that have been correctly converted to support Unicode.

Well, PHP boys and girls, this feels like quite a milestone: 50% of the 3084 functions that are bundled with PHP 6 have been upgraded to support and work safely with Unicode.

He includes a small chart beside the post as well showing where things are currently at like the safe vs unsafe functions.
