This is probably problem with UTF-8 encoding according to some similar issue. I ran the script (installed with pip) on Windows 10 with "Python 3.11.0 (main, Oct 24 2022, 18:26:48) [MSC v.1933 64 bit (AMD64)] on win32" on 2 UTF-8 files with czech characters. One file had CRLF line endings, the second one LF.
Full traceback:

The fix should be adding explicit
encoding="utf-8"parameters to functionopen, like stated in mentioned issue.
Hmm, after fixing the encoding in this way another error comes:
