count words in .doc,.docx with greek (unicode) characters

[lucky13]

Im building a web app using php and i have to count the words of an uploaded .doc or .docx file. So far im using the above functions in order to count the words but this code in not working for greek characters

for .doc

 public static function docWordCount($file){
  $fileHandle = fopen($file, "r");
  $line = @fread($fileHandle, filesize($file));   
  $lines = explode(chr(0x0D),$line);
  $outtext = "";
  foreach($lines as $thisline)
    {
      $pos = strpos($thisline, chr(0x00));
      if (($pos !== FALSE)||(strlen($thisline)==0))
        {
        } else {
          $outtext .= $thisline." ";
        }
    }
   $outtext = preg_replace("/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/","",$outtext);
  return str_word_count($outtext);
 }

If i use it with a .doc with greek characters i get an output this in the $outtext:
