Hi @Gadil-1987, and thank you for filing this issue. Given that the result is the same as copy-pasting directly from the document, this seems unlikely to be something pdfpumber can fix. It's possible that office-word is doing something special that this library could learn from, but I'm not sure what that would be. Closing for now, but feel free to continue the discussion here.
