    Hello, I opened a thread about this problem 3 months ago. I solved this problem.

    The problem was when I tried to generate some invoices I was getting an error message on a white page.

    Message: Invalid input characters. Did you set $mpdf->in_charset properly?

    When I looked at the Debug.log, I saw this.

    /public_html/wp-content/uploads/WOO-INVOICE/mpdf-pro/vendor/mpdf/mpdf/src/Mpdf.php on line 13178

    At line 13178 in mpdf.php

    $success = iconv($this->charset_in, ‘UTF-8//TRANSLIT’, $html);

    your code

    $success = iconv($this->charset_in, ‘UTF-8//IGNORE’, $html);

    It was fixed when I changed it to .

    Please have this fixed in the next release version.
