name = name.split('.')[0]
TypeError: a bytes-like object is required, not 'str'

list(extract_pages("aa.pdf"))

How can I run extract_pages() without having this error ?

Hi @astariul-colanim,

Thanks for raising the issue. I can replicate it with python tools/pdf2txt.py ~/Downloads/aa.pdf. This should not happen.

Its related to these issues:

• TypeError: a bytes-like object is required, not 'str'  #423
• TypeError: a bytes-like object is required, not 'str'. #277

(I prefer to keep them all open because we need to make sure the issue is fixed for each of the input pdf's)

Thanks @pietermarsman

Can you give me a pointer where can I monkey-patch the library to make it work ? (just a work-around is fine for me)
