Hello ,

I am using pypdf2 to extract Spanish text. I am using below code piece to do that. The problem is comes to in the part of these marks -> “ ” . In extractText part, ı get the throughput that format-> fi + someting + fl

For example -> “Quijote” : fiQuijotefl or “De la Mancha” : fiDe La Manchafl

I have tried to remove them as like that -> page_text= re.sub(r"['',\“\”\Œ]",'',page_text) Have not worked.
Is there any way to prevent it? Thanks.

import PyPDF2

pdfFileObj = open('X.pdf', 'rb')
text=[]
pdfReader = PyPDF2.PdfFileReader(pdfFileObj,strict=False)

for p in range(4,pdfReader.numPages):
    pageObj = pdfReader.getPage(p) 
    page_text=pageObj.extractText()
    text.append(page_text)
pdfFileObj.close()

#464 should help. Do you have an example pdf + expected output?

#924 improved the situation a lot. I suppose that the 2.1.0 release will fix this issue.

As there is no example PDF, I have no way to check. Hence I close this issue.

REL: 2.1.0
4e44122 
The highlight of the 2.1.0 release is the most massive improvement to the
text extraction capabilities of PyPDF2 since 2016 🥳🎊 A very big thank you goes
to [pubpub-zz](https://github.com/pubpub-zz) who took a lot of time and
knowledge about the PDF format to finally get those improvements into PyPDF2.
Thank you 🤗💚

In case the new function causes any issues, you can use `_extract_text_old`
for the old functionality. Please also open a bug ticket in that case.

There were several people who have attempted to bring similar improvements to
PyPDF2. All of those were valuable. The main reason why they didn't get merged
is the big amount of open PRs / issues. pubpub-zz was the most comprehensive
PR which also incorporated the latest changes of PyPDF2 2.0.0.

Thank you to [VictorCarlquist](https://github.com/VictorCarlquist) for #858 and
[asabramo](https://github.com/asabramo) for #464 🤗
