UnicodeDecodeError When Reading Non-ANSI Characters in PPTX Files

[ayoubelmhamdi]

I'm encountering a UnicodeDecodeError when attempting to read PPTX files that contain non-ANSI characters using pptx2md. Below is the error traceback:

pptx2md Radiobiologie.txt -t pptx.pptx 
Traceback (most recent call last):
  File "/tmp/new_1/venv/bin/pptx2md", line 8, in <module>
    sys.exit(main())
  File "/tmp/new_1/venv/lib/python3.12/site-packages/pptx2md/__main__.py", line 66, in main
    prepare_titles(args.title)
  File "/tmp/new_1/venv/lib/python3.12/site-packages/pptx2md/__main__.py", line 17, in prepare_titles
    for line in f.readlines():
  File "<frozen codecs>", line 322, in decode
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa1 in position 14: invalid start byte

This issue arises when the pptx2md command is run with a specific PPTX file as input. The error suggests that there is a problem with decoding a byte sequence that is not recognized as valid UTF-8.
