Thai language in PDF is square box
I just wanted to let you know that the issue appears to be with the font used on supporting the characters used by the Thai language. If Thai is your primary language, you can customize the HTML that generates the PDFs to use a different font that does support those characters. https://fossbilling.org/docs/customizing...nvoice_pdf Otherwise I'll be looking to see if we are able to ship it with a different font that offers a wider character support.
