Answer 1

Inspecting the provided example PDF one sees that the CIDSystemInfo entry for the DejaVuSans font embedded in the file is broken:

11 0 obj
<</Registry ‘7_wá
/Ordering ‘#x.<
/Supplement 0
>>

The values of Registry and Ordering should have been strings but here they are completely broken (even in an encrypted document strings have to be properly delimited).

This error has been fixed in the dompdf pull request 2114 in March 2020 which indeed is the fix for the dompdf issue 2060 pointed out by @Olivier in a comment to your question.

Thus, please update your dompdf version to a state that includes the above-mentioned pull request.
