[issue41941] Py_Initialize affects the console

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

PyConfig_InitIsolatedConfig() reduces side effects on the process. For example, it doesn't set the LC_CTYPE locale and it doesn't change the standard streams (stdio).

config_init_stdio() is not called in an isolated configuration:
