I got this error when I send NULL to ->multicell(). Sending "" fixed it.

This works for me:

Use

autoScriptToLang = true;
autoLangToFont = true;

    include("mpdf-6.0.0/mpdf.php");
    $mpdf = new mPDF('c', 'A4', '', '', 0, 0, 0, 0, 0, 0);
    
    $mpdf->autoScriptToLang = true;
    $mpdf->autoLangToFont   = true;

    $mpdf->WriteHTML($html);
    $mpdf->Output('SavePDF.pdf', 'D');

I'm 99% sure that problem is because you did some manipulations with the text using unicode-unsafe functions. Use mb_strpos()/mb_substr() instead of strpos()/substr(), and add "/u" modifier to all your conversions with prog_replace().

Of course, the problem can be fixed by allowing "charset conversion" as already suggested before. But much better to know that your text already correct and meets the compliance of UTF-8.

After hours of hair-pulling, this worked wonders for me :)

(In my case बोटोक्स was showing as ??????)

$mpdf->SetAutoFont();

$mpdf = new mPDF('utf-8','', 0, '', 15, 15, 16, 16, 9, 9, 'L');
$mpdf->SetAutoFont();

//~ Nothing of below worked :(
//~ $mpdf->useLang = true;
//~ $mpdf->autoScriptToLang = true;
//~ $mpdf->autoLangToFont = true;
//~ $pdf_html = mb_convert_encoding($html, 'UTF-8', 'UTF-8');

$mpdf->WriteHTML($html);
//~ $mpdf->DeletePages(2);
$filename   = date('ymdhis').".pdf";
$mpdf->Output($filename,'D');

My PDF included a mix of English and Hindi words like

"3 units of बोटोक्स Priced @ $10.00/unit".

The below two lines will do the trick 

$mpdf->allow_charset_conversion = true;
$mpdf->charset_in = 'iso-8859-4';

Add the above two lines after creating the object , this will look like

$mpdf=new mPDF();
$mpdf->allow_charset_conversion = true;
$mpdf->charset_in = 'iso-8859-4';

With mpdf it is no point in conversions and encoding as these most likely will lose your chars and you would get only "?" or other unrecognisable chars (but will yield output)

Try using these before any input being send to mpdf:

$mpdf->allow_charset_conversion=true;
$mpdf->charset_in='UTF-8';

Try this

$html = mb_convert_encoding($html, 'UTF-8', 'UTF-8');

before calling: "$mpdf->WriteHTML($html);"

It's seems senseless, but it works for me.

Use utf8_encode() function. Eg : $html = '

Name of Originator

Originator Address

Originator Phone Number

Originator Email

Borrower

Property Address

Date of GFE

 Â

'; $html = utf8_encode($html1);
