Inconsistent behavior for copy protection
I use Poppler 0.83
I have an encrypted document where PdfInfo.exe returns:
Encrypted = "yes (print:yes copy:no change:no addNotes:no algorithm:RC4)"
The very weird thing is that PdfToText.exe returns the text without problems.
But PdfToHtml.exe returns "Permission Error: Copying of text from this document is not allowed."
Why can one tool read the PDF file and the other tool cannot ?
This does not make any sense.
I can also open the same document in Chrome, click 'Print' --> 'Save as PDF' and I get a document which has copy protection disabled. Chrome uses PDFium.
If PDFium is able to do that, why can't Poppler ?
