Question to someone who's familiar with how arrays are implemented in PHP. I've tried asking this on stackoverflow.com, but it looks like I need to ask this one to people familiar with PHP source. PHP manual says that one should only use strings or integers as array keys. Also I know that PHP doesn't speak unicode yet. So - I was just wondering - when unicode characteres are used in array key - does PHP strips them or affects them in any way? or does iPHP simply treats keys as binary string, the end of the story?
