Replacement Text (AccSupp ActualText entry) Support
We noticed that your PDF viewer doesn't have AccSupp ActualText support. This means that copy-pasting technical text such as shellscripts and programming code, does not work in your PDF viewer and this greatly restrains the use of your whole program.
The replacement text is said to be supported, according to the file "Document management - Portable document format - Part 1: PDF 1.7" both on Table 323, page 559, and on section 14.9.4, page 615. Available here: https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf.
But according to the tests made using PDFs produced by pdflatex using the package accsupp, the replacement text support seems to be unreliable at the moment for copy and paste.
The tests are shown here: https://github.com/ho-tex/accsupp/issues/2
The tests generated various behaviors such as:
- Correct copy and paste of the text, but incorrect copy and paste of leading spaces and empty lines (Test 1);
- Unexpected insertions of spaces (Test 3 and Test 6), and;
- Spaces turned into newlines (Test 4).
We kindly request better support of the replacement text support, because the copy and paste directly from the PDF document is not reliable.

I understand your concern here. I have shared this with the higher management. We currently do not have any plan to implement it but we have kept it in our radar and will pick up in future,
