+ If set to the value ``0``, causes the main Python command line application
+ to skip coercing the legacy ASCII-based C locale to a more capable UTF-8
+ based alternative. Note that this setting is checked even when the
+ :option:`-E` or :option:`-I` options are used, as it is handled prior to
+ the processing of command line options.
+
+ If this variable is *not* set, or is set to a value other than ``0``, and
+ the current locale reported for the ``LC_CTYPE`` category is the default
+ ``C`` locale, then the Python CLI will attempt to configure one of the
+ following locales for the given locale categories before loading the
+ interpreter runtime:
+
+ * ``C.UTF-8`` (``LC_ALL``)
+ * ``C.utf8`` (``LC_ALL``)
+ * ``UTF-8`` (``LC_CTYPE``)
+
+ If setting one of these locale categories succeeds, then the matching
+ environment variables will be set (both ``LC_ALL`` and ``LANG`` for the
+ ``LC_ALL`` category, and ``LC_CTYPE`` for the ``LC_CTYPE`` category) in
+ the current process environment before the Python runtime is initialized.
+
+ Configuring one of these locales (either explicitly or via the above
+ implicit locale coercion) will automatically set the error handler for
+ :data:`sys.stdin` and :data:`sys.stdout` to ``surrogateescape``. This
+ behavior can be overridden using :envvar:`PYTHONIOENCODING` as usual.
+
+ For debugging purposes, setting ``PYTHONCOERCECLOCALE=warn`` will cause
+ Python to emit warning messages on ``stderr`` if either the locale coercion
+ activates, or else if a locale that *would* have triggered coercion is
+ still active when the Python runtime is initialized.
