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.

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. Those tests are available on the referenced accsupp github page in the end of this text.

We kindly request better support of the replacement text support, because the copy and paste directly from the PDF document is not reliable.

Please also refer to these two pages for further discussion:
