How to generate PDF in different languages?

Question

Hi,

I want to generate a PDF with the help of few selection in form and an XML file that contains users country specific template in different languages.

I am able to generate the printable version of the file but PDF does not seem to be working for some of the characters [chinese, Japanese Korean and Taiwanese].

I am using TCPDF and added "unbatang_0613.ttf" fonts in pdf_fonts folder. I think i am missing the right .ttf or .otf file.

Any help on this would be of great help

Thanks in advance.
