[New-bugs-announce] [issue46171] venv module produces spurious warning that location has moved

[layday]

New submission from layday <layday at protonmail.com>:

After https://github.com/python/cpython/commit/6811fdaec825bd6ab64e358a4b480108f5634d2d
the venv module produces spurious warnings for venv paths which contain
DOS-encoded parts e.g. "USER\~1" in "C:\Users\USER~1".
`tempfile.gettempdir()` returns legacy paths like these for
user temp dirs.

MRE:

    python -c "import tempfile
    import venv

    venv.create(tempfile.mkdtemp())"
    Actual environment location may have moved due to redirects, links or junctions.
    Requested location: "C:\Users\RUNNER~1\AppData\Local\Temp\tmpfoobar\Scripts\python.exe"
    Actual location:    "C:\Users\runneradmin\AppData\Local\Temp\tmpfoobar\Scripts\python.exe"
