I download a file of pdf and the pdf use GPL Ghostscript 8.15 When I copy and paste the content(chinese word), I want to use the file some word change something. Then the word only change the code.
All I can tell you is that Ghostscript is not a PDF editor. I don't know what other software you could use to alter the PDF contents (if that's what you're trying to do, I can't quite tell). Sorry. Good luck, Karl
