fopen can't read arabic characters - ms-word

Question

This function reads (document.doc) files.. But it turns arabic characters into english characters
I want to make it read arabic characters , Or remove it at least.
function word($filename){
if(($fh = fopen($filename, 'r')) !== false ) {
$headers = fread($fh, 0xA00);
$n1 = ( ord($headers[0x21C]) - 1 );
$n2 = ( ( ord($headers[0x21D]) - 8 ) * 256 );
$n3 = ( ( ord($headers[0x21E]) * 256 ) * 256 );
$n4 = ( ( ( ord($headers[0x21F]) * 256 ) * 256 ) * 256 );
$textLength = ($n1 + $n2 + $n3 + $n4);
if($extracted_plaintext = #fread($fh, $textLength)){
}else{
return docx2text($filename); // Save this contents to file
}
$text=str_replace( chr(13) , "\n", $extracted_plaintext);
echo $text;
}
}
word('filename.doc');
E.X: filename.doc -> file contains statment "بسم الله الرحمن الرحيم"
