For those who have troubles in displaying UCS-2 data on browser, here's a simple function that convert ucs2 to html unicode entities :

<?php

 function ucs2html($str) {
    $str=trim($str); // if you are reading from file
    $len=strlen($str);
    $html='';
    for($i=0;$i<$len;$i+=2)
        $html.='&#'.hexdec(dechex(ord($str[$i+1])).
                   sprintf("%02s",dechex(ord($str[$i])))).';';
    return($html);
 }
?>
