PHP mPDF: Failed to display Yiddish Language in PDF

Question

I'm using mPDF in codeigniter project. It's working well for English and Russian language but in Yiddish language it's showing only dots (.) and commas (,) like below:

mPDF output

While the content I'm writing in it is:

Yiddish Content

Here is my code:

    $mpdf = new \Mpdf\Mpdf();
    $mpdf->SetFont('avenirnext');
    $mpdf->SetTitle($title);
    $mpdf->SetAuthor('Blavatnik');
    $mpdf->WriteHTML($stylesheet, 1);
    $mpdf->WriteHTML($stylesheet2, 1);
    $mpdf->WriteHTML($stylesheet3, 1);
    $mpdf->setAutoTopMargin = 'stretch';
    $mpdf->SetHtmlHeader($header, 'OE');
    $mpdf->SetHTMLFooter($footer, 'OE');
    $mpdf->WriteHTML($html);
    if ($html2 != '' && $html3 != '') {
        $mpdf->SetHtmlHeader($secondHeader, 'OE');
        $mpdf->WriteHTML($html2);
        $mpdf->SetHtmlHeader($header, 'OE');
        $mpdf->WriteHTML($html3);
    }
    if ($transcriptHtml2 != '' && $transcriptHtml3 != '') {
        $mpdf->WriteHTML($transcriptHtml2);
        $mpdf->WriteHTML($transcriptHtml3);
    }
    $mpdf->Output($title . '.pdf', 'I');

I've also tried using below solution:

$mpdf = new mPDF('utf-8');
$mpdf->SetDirectionality('rtl');

What else I can change it it to make it work for all language or mainly this Yiddish language. Thanks!

Answer 1

You have to use a font supporting hebrew characters. Furthermore, avenirnext is not in a standard distribution and you have not configured an additional font.

Remove the SetFont call and use

$mpdf->autoLangToFont = true;

along with lang="yi" or lang="he" in a div or a span around your hebrew/yiddish text.

You can also find example code in a autofont mPDF example file.
