I recognize Python 3.13 is still relatively new and some packages, e.g., srsly (explosion/srsly#112), don't work with it yet. I would be willing to remove it from the build-pipeline until 3.13.1 is released, or the issue with srsly is resolved.

Edit

I removed Python 3.13 from the workflow.

I'm running local tests to see if the package will build on the new versions. On Python 3.10, test_vocab_file fails with the following UnicodeDecodeError:

FAILED contextualSpellCheck/tests/test_contextualSpellCheck.py::test_vocab_file - UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 13373: character maps to <undefined>

I can get past the error by changing the following line, but this still results in a failed test.

- with open(orgDebugFilePath) as f1:
+ with open(orgDebugFilePath, encoding="latin1") as f1:

Taking a step back, what is the purpose of the following assert statement?

def test_vocab_file():
    ...
    with open(orgDebugFilePath) as f1:
        with open(debugPathFile) as f2:
            assert f1.read() == f2.read()

Edit

I understand now—you're checking that the ContextualSpellCheck correctly writes to the "debugFile.txt" when debug=True.

I was able to get the test (test_vocab_file) to pass by setting encoding="utf8". See 6f8bde1.
