Missing whitespaces between words

[lwollenbergfuzzy]

While reading a PDF, we encountered a problem where white spaces between words were missing.

The enviorment is the following:
pypdf==5.7.0,
crypt_provider=('cryptography', '45.0.4'),
PIL=11.2.1

To reproduce the problem use the following code:

import pypdf
from pathlib import Path

pdf_path = Path("PSIqualicision_A2_v1.7.1_202502131610_p13.pdf")
with pdf_path.open("rb") as pdf_file:
    pypdf_reader = pypdf.PdfReader(pdf_file)
    page = pypdf_reader.get_page(0)
    print(page.extract_text())

which results in the following output:

The line in question looks like this in the PDF:

Did you try to set space_width to another value or tried the layout mode?

Nevertheless, text extraction is an evergreen, as documented as well: https://pypdf.readthedocs.io/en/stable/user/extract-text.html#whitespaces
