Ok, the missing link is that the python you run into needs to be also a symlink venv:

❯ py -m venv env --without-pip --clear --symlinks
❯ .\env\Scripts\python.exe -c "import venv, subprocess; venv.EnvBuilder(with_pip=False, symlinks=True).create('venv'); subprocess.check_call(['venv\\Scripts\\python.exe', '-Ic', 'import sys; print(sys.executable)'])"

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'
