I understand it so I proposed per-install UTF-8 mode. User can set PYTHONUTF8=1 user environment variable for now. But it may break existing applications. My proposal is per-environment UTF-8 mode. When user want to install new Python to learn Python, they can enable UTF-8 mode only for the new Python environment without breaking existing applications. >> * Put a checkbox in the installer? > > Do I want Python to assume that everything is UTF-8? Probably not. > Even you don't want, many developers assume default is always UTF-8 already. And you can enable UTF-8 mode only in one venv to run such code, if UTF-8 mode can be enabled by pyvenv.cfg. -- Inada Naoki <songofaca...@gmail.com> _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/O3H7N5FSV2QT6PFJDTBBKPLO3JSTTVBS/ Code of Conduct: http://python.org/psf/codeofconduct/
