If the filepath starts with something that is not valid utf-8, it would
have returned "". And if the filepath was all non-valid utf-8, it would
also return "".
Test suite is failing in windows in conflict resolution tests, where the
automatic conflict resolution adds in a .variant file. On windows, those
files are somehow missing. I don't understand why, and the test failures
only happen on appveyor and not in a local windows VM.
So, since replaceFile was recently changed to remove a windows specific
ifdef, put it back, to see if that is somehow causing these failures.
With old:
Cache entry not found: C:\projects\git-annex\Users\appveyor\.stack
I think fixing this will result in caching preventing a full rebuild of
git-annex each time.
I hope that the windows test suite failure on appveyor was fixed by
updating to a newer windows there. I have not been able to reproduce
that failure in a windows 11 VM run locally.
When an UNC-style path is passed into openTempFile, the returned file
starts with that same style of path. Which can cause problems, eg piping
that filename to git failed. So, convert the output filename to be
relative to the input temp directory.

This was an attempt at continuing the RawFilePath transition into an
OsPath transition. Unforunately, it had multiple test suite failures on
windows. Debugging those seems that it would be more work than the
minor optimisation value of this.
Test suite failure looks like this:

This is apparently in Git.HashObject, and probably in hashBlob, which uses a
temp file with a name starting with "hash", but I have not been able to tell
what's wrong.
I don't understand where the "\\?" path prefix (windows UNC-style path)
is coming from in the path that gets fed into git hash-file, or why git
hash-file can't open the file.
