Previously the buildpack would set the `LANG` env var at build and run time to the value `C.UTF-8`, to match the official Docker Python images. However, the env var should not be needed for modern Python, and so the official Docker Python images no longer set it: docker-library/python#887 docker-library/python#895 In addition, the older issues typically only affected other distros such as alpine, or environments where someone had overridden the system locale, which doesn't apply to the Heroku base images.
