At the moment if you pass a `Path` object, the `source` will not be encoded in, only if a string is passed in. Given there is already a function to handle this, `_normalize_path`, I've simplified the logic to just run that over the `str/Path` to ensure it is always encoded.

- [x] Closes #5888

I'm not sure if this needs including in the `whats-new.rst`. I'm happy to add it if desired.
