Running `pipreqs .` in the `python\FontTools` venv results in the following:

Can someone please help me fix this?

Reproduce `pipreqs .` in the reported Python 3.10.11 virtual environment, then inspect pipreqs.py around get_all_imports and line 115 where the file is read. Done means the command processes the project without the reported UnicodeDecodeError.
