[TYPO3-50-general] PHP6 array keys unicode issue

[Robert Lemke]

Hey bleeding-edge-PHP-users,

I just stumbled over a weird behaviour with PHP6. Consider the  
following code (with unicode_semantics
enabled):

<?php
preg_match('/(?P<character>\w),/', 'a,b,c,d', $matches);
echo (isset($matches[(binary)'character']) ? 'yes ' : 'no ');
echo (isset($matches[(unicode)'character']) ? 'yes ' : 'no ');

$matches = array('character' => 'a');
echo (isset($matches[(binary)'character']) ? 'yes ' : 'no ');
echo (isset($matches[(unicode)'character']) ? 'yes ' : 'no ');
?>

The regular expression creates an associative array with "character"  
as the key.
My expected output is:

no yes no yes

But it is

yes no no yes

The preg_match seems to use a "binary" string as the index while my  
manual assignment
uses a unicode string.

The question is if that is a wanted behaviour and if we can rely on  
that. I just wanted
to hear your opinion about it before I ask in one of the PHP lists ...
