try this, set utf-8 before getting result both mysqli query , header

1. $mysqli->set_charset("utf8"); 

and

2.  header('content-type: application/csv');     header('content-disposition: attachment; filename=' . $filename);     header("content-transfer-encoding: utf-8");     header('pragma: no-cache');
