I'm not sure that it works this way. preconfig_get_global_vars() ignores Py_UTF8Mode if Py_UTF8Mode <= 0.

Py_UTF8Mode should not be used: PyPreConfig.utf8_mode should be used instead. Today, it seems like the only purpose of Py_UTF8Mode is to explicitly enable the Python UTF-8 Mode with Py_UTF8Mode=1.

If set to -1, look for the :option:`-x` option and the :envvar:`PYTHONUTF8` environment variable.
