These characters are not undefined. 0x80-0x9f are the C1 control

Lastly, you have several bare "except" clauses in the code. Bare
excepts are almost always incorrect. I appreciate that it's not easy
to predict exactly what exceptions might turn up here (although I
posit that for all of these, subsets of (TypeError, KeyError,
AttributeError, IndexError) are sufficient), but at the very minimum
you should specify "except Exception", so that you're not
inadvertently catching things like SystemExit and KeyboardInterrupt.
Cheers and hope this is helpful,
