Using Free Mono (UTF-8 Unicode) generate errors [solved]

[ironbone]

I tried to use  Free Mono (UTF-8 Unicode) . Unfortunately when I try to generate the PDF invoice then  all the time have the following error:
TCPDF ERROR: Could not include font definition file: freemono

I use
VirtueMart 3.4.2
Joomla  3.9.10
com_tcpdf_1.0.8

Still the same problem with the version 3.6.0 of VM

The problem is not VM. Another plugin load another instalation of  tcpdf library before the VM does.
In my case it was System - DPCalendar plugin
