DocumentInformation.title sometimes return bytes instead of str #2929
Description
I am reading a PDF file from:
https://www.ms-ad-hd.com/en/ir/ir_event/event/presentation/main/01111119/teaserItems1/00/linkList/00/link/20220810Tranverse%20QA%20Summary.pdf
The "title" for this doc returns bytes instead of str, although the method should always return str.

pdf_reader = pypdf.PdfReader(io.BytesIO(response.content))
