What steps will reproduce the bug?

1. Create a directory with a name containing an umlaut character, e.g. lärm
2. Create a package.json file in it, with a test script.
3. Run node --run test

How often does it reproduce? Is there a required condition?

• OS has to be Windows, on Linux the issue is not reproducible
• A pathname with an umlaut character in it.

What is the expected behavior? Why is that the expected behavior?

It should execute the test script in the package.json file.

What do you see instead?

D:\D\lärm>node --run test
Can't find package.json for directory D:\D\lõrm

Most likely related to #56049 and std::filesystem::path. I'll take a look at it.

I'm a little new to the repo though, so I'm not quite sure where to start looking first.
