ValueError: invalid literal for int() with base 10: b'0,0'

[DL6ER]

See #1269 for further details, this reports another issue I've come accross.

Environment

Which environment were you using when you encountered the problem?

$ python -m platform
Linux-5.4.0-122-generic-x86_64-with-glibc2.29

$ python -c "import PyPDF2;print(PyPDF2.__version__)"
2.10.3

Code + PDF

This is a minimal, complete example that shows the issue:

import PyPDF2
with open("main.pdf", "rb") as f:
  pdfreader = PyPDF2.PdfFileReader(f, strict=False)
  full_content = " ".join([page.extractText() for page in pdfreader.pages])

PDF used above: main.pdf

Traceback

This is the complete Traceback I see:

[DL6ER]

Closing this issue as it is very similar to #1270

@DL6ER
This issue may be different from #1270 : '0,0' means some data have been extracted and there could be an issue in the data analysis. I recommend it to be reopened

The PDF can be opened and read by Evince + Google chrome. So I guess we should also be able to do it in non-strict mode. I reopen it as a robustness issue.
