-.. function:: set_conversion_mode(encoding, errors)
-
- This function sets the rules that ctypes objects use when converting between
- bytes objects and (unicode) strings. *encoding* must be a string specifying an
- encoding, like ``'utf-8'`` or ``'mbcs'``, *errors* must be a string specifying
- the error handling on encoding/decoding errors. Examples of possible values are
- ``'strict'``, ``'replace'``, or ``'ignore'``.
-
- :func:`set_conversion_mode` returns a 2-tuple containing the previous
- conversion rules. On windows, the initial conversion rules are ``('mbcs',
- 'ignore')``, on other systems ``('ascii', 'strict')``.
-
- You can set the *encoding* to ``'undefined'`` to completely disable automatic
- conversions.
