 * You need to install [mbstring ](https://github.com/baselbers/woocommerce-pdf-invoices/issues/81)
   module. Ask your hosting.

 * Hi,
 * Well, it should [work ](https://github.com/mpdf/mpdf/issues/272)with the module.
   What version of PHP are you using?
    Did you restart web server/php service?

 * Your hosting can help you with this kind of problems.
    Unfortunately I can’t 
   do anything about it. It should work if the module is correctly installed and
   enabled.
