Special characters become "?" On PDF report
There's an issue when exporting special characters to PDF format on civicrm report. All special characters turn into "?".
This problem can be replicated on https://dmaster.demo.civicrm.org.
After discussing the problem on do-ocracy 2020 channel, we found out that dejavu fonts were removed on dompdf fonts folder to save about 12mb for civicrm. Thus, this issue emerged.
