# The following 2 patches fix the test suite failing on nix < 2.3 with
# Python < 3 because those nix versions do not run in a pseudoterminal,
# which makes Python 2 not set the default encoding to UTF-8, and the
# Babel code crashes when printing a warning in that case.
# See #75676 and https://github.com/python-babel/babel/pull/691.
# It is important to fix this because otherwise Babel is not buildable
# with older nix versions (e.g. on machines used as --builders).
# TODO: Remove at release > 2.8.0.
