How to output Cyrillic mPDF?

Question

PHP

Hello! I've scoured the internet but haven't found a working solution. The bottom line is that the following script is on the server:

$html =  $_POST['content'];
    $filename = $_POST['filename'] . '.pdf';
    $mpdf = new mPDF();
    $mpdf->charset_in = 'utf-8';
    $mpdf->writeHTML($html);
    $mpdf->Output($filename, 'D');

refuses to display Cyrillic. On the local openServere works fine.

Answer 1

And what encoding comes to Post? And head did? Try. I have tons of Cyrillic output on mpdf, even without charset_in. Probably not utf comes to the post.
