Another test: try to build a venv to get pip:
Building a venv is ok. Good, our stdlib is not so bad :-)
$ PYTHONWARNINGS=error::EncodingWarning ./python -W error::EncodingWarning -m

But ensurepip fails soon:
$ PYTHONWARNINGS=error::EncodingWarning ./env/bin/python -W
error::EncodingWarning -m ensurepip --verbose
