Getting TypeError: ord() expected string of length 1, but int found error

Question

Code is

from PyPDF2 import PdfFileReader
with open('HTTP_Book.pdf','rb') as file:
    pdf=PdfFileReader(file)
    pagedd=pdf.getPage(0)
    print(pagedd.extractText())

This code raises the error shown below:

TypeError: ord() expected string of length 1, but int found

I searched on internet and found this Troubleshooting "TypeError: ord() expected string of length 1, but int found" but it doesn't help much. I am aware of what is the background of this error but not sure how is it related here?

Tried changing the pdf file and it works fine. Then what is wrong: pdf file or PyPDF2 is not able to handle it? I know this method is not much reliable as per documentation:

This works well for some PDF files, but poorly for others, depending on the generator used

How should this be handled?

I got the issue. This is just a limitation of PyPDF2. I used tika and BeautifulSoup to parse and extract the text, it worked fine. Although it needs little more work.

from tika import parser 
from bs4 import BeautifulSoup
raw=parser.from_file('HTTP_Book.pdf',xmlContent=True)['content']
data=BeautifulSoup(raw,'lxml')
message=data.find(class_='page') # for first page
print(message.text)
