    """Make sure that a string is a byte string

:arg obj: An object to make sure is a byte string.  In most cases this
        will be either a text string or a byte string.  However, with
        ``nonstring='simplerepr'``, this can be used as a traceback-free
        version of ``str(obj)``.
    :kwarg encoding: The encoding to use to transform from a text string to
        a byte string.  Defaults to using 'utf-8'.
    :kwarg errors: The error handler to use if the text string is not
        encodable using the specified encoding.  Any valid `codecs error
        handler <https://docs.python.org/3/library/codecs.html#codec-base-classes>`_
        may be specified. There are three additional error strategies
        specifically aimed at helping people to port code.  The first two are:

:surrogate_or_strict: Will use ``surrogateescape`` if it is a valid
                handler, otherwise it will use ``strict``
            :surrogate_or_replace: Will use ``surrogateescape`` if it is a valid
                handler, otherwise it will use ``replace``.

Because ``surrogateescape`` was added in Python3 this usually means that
        Python3 will use ``surrogateescape`` and Python2 will use the fallback
        error handler. Note that the code checks for ``surrogateescape`` when the
        module is imported.  If you have a backport of ``surrogateescape`` for
        Python2, be sure to register the error handler prior to importing this
        module.

The last error handler is:

:surrogate_then_replace: Will use ``surrogateescape`` if it is a valid
                handler.  If encoding with ``surrogateescape`` would traceback,
                surrogates are first replaced with a replacement characters
                and then the string is encoded using ``replace`` (which replaces
                the rest of the nonencodable bytes).  If ``surrogateescape`` is
                not present it will simply use ``replace``.  (Added in Ansible 2.3)
                This strategy is designed to never traceback when it attempts
                to encode a string.

The default until Ansible-2.2 was ``surrogate_or_replace``
        From Ansible-2.3 onwards, the default is ``surrogate_then_replace``.

:kwarg nonstring: The strategy to use if a nonstring is specified in
        ``obj``.  Default is 'simplerepr'.  Valid values are:

:simplerepr: The default.  This takes the ``str`` of the object and
            then returns the bytes version of that string.
        :empty: Return an empty byte string
        :passthru: Return the object passed in
        :strict: Raise a :exc:`TypeError`

:returns: Typically this returns a byte string.  If a nonstring object is
        passed in this may be a different type depending on the strategy
        specified by nonstring.  This will never return a text string.

.. note:: If passed a byte string, this function does not check that the
        string is valid in the specified encoding.  If it's important that the
        byte string is in the specified encoding do::

encoded_string = to_bytes(to_text(input_string, 'latin-1'), 'utf-8')

.. version_changed:: 2.3

Added the ``surrogate_then_replace`` error handler and made it the default error handler.
