If that source is causing that error it's not because of the kanji sequences. You've got an extra comma (,) at the end of your array() statement.

Your code:
$foo = array (
         'One Text' => 'some kanji',
         'Another Text' => 'more kanji',
       );

The last comma, should not be present, as PHP expects another argument to follow it. Simply remove it:
$foo = array (
         'One Text' => 'some kanji',
         'Another Text' => 'more kanji'
       );

On a related note, if you wish to code using non-western character sets, full Unicode support is being added into PHP5 (most likely, the next major release after 5.1 will have it). This should be of great use to you when it's released.

Nicholas, that is bullshit. You can have trailing comma's in arrays - just like in C. And Unicode is also not added in PHP 5 or PHp 5.1. Please refrain from commenting if you're not 100% sure about things.

This was a very stripped down version, if I exchange the kanji with say "abc", it works fine. It also works with other kanji sequences, katakana, hiragana ect. 

These two samples is the only two out of about 75 causing problems

It's because in latin one it looks like this:
'One Text'=>'‹@”\',

you see the \ in the last char 能 escaping the '.

So this is not a bug as PHP simply doesn't support this yet.

Any idea when to expect support for this ? 
Will need to develop a workaround tomorrow anyway as we need the given kanji's in the included language file
