The problem is extremely simple and can be reproduced anytime. I was trying to copy the title from the PDF and using that clipboard to rename the PDF but whenever I was trying to do that I was getting error like - "A file name can't contain any of the following characters: /:?"<>|". I am pretty sure there are no such characters in the PDF title. Also, when I paste the text into some text editor(notepad,MS-word,google search bar) and then copy again the text to rename the PDF, it works.
Why this happens?
Operating system: Windows 10 Application: Adobe PDF
