How to display data that is with UTF-8 character while exporting it to .xls (EXCEL) file

Question

<?php
$month=$_REQUEST["month"];
include 'include/myfunc.php';
$sql = "SELECT * FROM announcement WHERE month='".$month."'";
$result = mysqli_query($con,$sql);
$status="";
$html='<table><tr><td>Date</td><td>Announcement Detail</td><td>Tag</td><td>Amount</td><td>Status</td><td>File Name</td></tr>' ;

while( $row = mysqli_fetch_array($result) )
{
    if ($row['status']=="active") {
      $status = "निरकर्त";
    }else{
        $status = "लंबित";
    }
    
    $html.='<tr><td>'.$row['date'].' '.$row['month'].' '.$row['year'].'</td><td>'.$row['announcement_detail'].'</td><td>'.$row['tag'].'</td><td>'.$row['amount'].'</td><td>'.$status.'</td><td>'.$row['file'].'</td></tr>' ;
}
$html.= '</table>';
header('Content-Type:application/xls');
header('Content-Disposition:attachment;filename=report.xls');

echo $html;
?>

When exported, it is showing something like this निरकरà¥à¤¤ I have tried putting in this header("content-type:application/xls;charset=UTF-8"); Still m getting only the garbage value. Can anyone help me on what exactly I should do so that data displays properly irrespective of whether user has stored data in English or Hindi.

Instead of doing echo you have convert it like this and it will work.

print chr(255) . chr(254) . mb_convert_encoding($html, 'UTF-16LE', 'UTF-8');
