@hupili Could you please help us ?

[hupili]

may try other tools like “pandoc”

[lullabymia]

Does pandoc also accept files in commonmark, creole, docbook, docx, epub, fb2, gfm, haddock, html, jats, json, latex, man, markdown, markdown_github, markdown_mmd, markdown_phpextra, markdown_strict, mediawiki, muse, native, odt, opml, org, rst, t2t, textile, tikiwiki, twiki, vimwiki (no pdf)

How about following two resources?

• https://www.jianshu.com/p/31939ee6f1c9
• https://github.com/wshuyi/demo-pdf-content-extract-batch-python-pdfminer/blob/master/pdf_extractor.py

[ChicoXYC]

I‘ve already tried this method before, and tested it again today, didn't work out.

from pdfminer.pdfpage import PDFPage

error:

 No module named 'pdfminer.pdfpage'

and

TypeError: __init__() got an unexpected keyword argument 'codec'
# didn't find the solution

[hupili]

how about importing pdfminer alone?

[ChicoXYC]

Yes, I tried this module alone. Same problem above. Didn't work out for Chinese

[hupili]

do you mean pdfminer works for English?

[ChicoXYC]

NO. english don't work either. It seems that the module function has been changed and I haven't found the answer. But pypdf2 works for English.
