Of course, here you are. My Unicode dejavusans font is added, I commented some points useless for me. You can make it refined or better coded. Regards :)

Re: How Joomla 3.8 generates PDF now? Lack of pdf.php, new libraries structure
« Reply #16 on: September 26, 2019, 21:49:13 pm »
With recent upgrades (now on Joomla 3.9.11 and VM 3.6.2) I found I needed to update all my code that directly uses tcpdf as it was moved
from /libraries/tcpdf
to /libraries/vendor/tecnickcom/tcpdf

Notice also /config/lang is no longer included - not required anymore, I commented out the require_once to the /config/lang/eng.php and my PDFs continue to work fine again, mind you I'm not using multiple languages presently. My code:
Code: [Select]
//load the pdf creator as already installed in libraries
ob_start(); // clear the php buffer needed to stop warning for 'headers already sent'
//require_once( JPATH_BASE . '/libraries/vendor/tecnickcom/tcpdf/config/lang/eng.php' );
require_once( JPATH_BASE . '/libraries/vendor/tecnickcom/tcpdf/tcpdf.php' );
