Is chardet needed?

[DLawrenceQQ]

HI everyone. I was looking at the licenses of dependencies and if using pypdfium/pdfium as the backend it looks like they are all MIT/BSD/Apache or versions/variations on those flavors.

Chardet is (LGPLv2+) (LGPL) which affects how i want to package my software piece.
If i remove chardet nothing seems to break.. I think because it is using charset_normaliser which is an MIT license...but maybe it is broken and i just haven't realised it yet?

Is there an expectation that chardet is needed?
