Wplms Pdf Certificate: Tcpdf Utf-8 Bad Encoding With Special Characters Displays on Pdf Certificate

If Something strange is happening with your pdf certificate, If you are using languages for pdf certificate like greek, Latin, Russian, Lithuanian, Turkish, Chinese, Hindi etc. and while generating pdf certificate you get few of its characters and other remains special symbols like this ??????.

Then the question arises what should we do now??

TCPDF is quite tricky with utf8. Best way to achieve what you want is to embed the font in the generated PDF file itself. You can use FreeSerif/ OpenSans font from the TCPDF package, it contains all the utf-8 symbols, shows absolutely any character of any language. That’s probably the easiest way to get symbols you need.

You could also make your own font to embed, containing the characters you need. That’s probably the best solution, keeping it universal and small in size, but is more complex.
