Text extraction incomplete on Linux (resolution: missing system font) #288
-
|
The library's text extraction produces different results when used on Win 11 and Ubuntu. I use the same version pypdfium2==4.22.0 import pypdfium2
docs = []
path_file = '...'
pdf_reader = pypdfium2.PdfDocument(path_file, autoclose=True)
for page_number, page in enumerate(pdf_reader, start=1):
text_page = page.get_textpage()
content = text_page.get_text_range()
docs.append(content)
text_page.close()
page.close()
pdf_reader.close()
How can I fix this error? |

Our Unfortunately I can't really comment on the behavior of external code.

That said, I wonder if this issue could possibly be handled by the end user installing some system font package? |

Yes so do I. I will try installing some more fonts into the system to test. Thank you! |

No, I don't have access to windows (except CI) -- but according to your report it works, right? |

I believe the culprit might be proprietary Windows fonts such as Arial and TimesNewRoman which distros can't ship for licensing reasons - so the PDF viewer substitutes with some other available font, which might not have the special chars. See the attached inspection screenshot from Okular |

I installed the font into my Ubuntu system and it worked. Thank you for your help! |

Presumably it would work if you copy over the Windows fonts to Ubuntu.
