Fopen can't read arabic characters

PHP
1

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) , "\
", $extracted_plaintext);

		echo $text;
    }
	
	
}

word('filename.doc');
