    Helper function to format and quote a single header parameter using the
    strategy defined in RFC 2231.

    Particularly useful for header parameters which might contain
    non-ASCII values, like file names. This follows
    `RFC 2388 Section 4.4 <https://tools.ietf.org/html/rfc2388#section-4.4>`_.

    :param name:
        The name of the parameter, a string expected to be ASCII only.
    :param value:
        The value of the parameter, provided as ``bytes`` or `str``.
    :ret:
        An RFC-2231-formatted unicode string.

    Helper function to format and quote a single header parameter using the
    HTML5 strategy.

    Particularly useful for header parameters which might contain
    non-ASCII values, like file names. This follows the `HTML5 Working Draft
    Section 4.10.22.7`_ and matches the behavior of curl and modern browsers.

    .. _HTML5 Working Draft Section 4.10.22.7:
        https://w3c.github.io/html/sec-forms.html#multipart-form-data

    :param name:
        The name of the parameter, a string expected to be ASCII only.
    :param value:
        The value of the parameter, provided as ``bytes`` or `str``.
    :ret:
        A unicode string, stripped of troublesome characters.

        A :class:`~urllib3.fields.RequestField` factory from old-style tuple parameters.

        Supports constructing :class:`~urllib3.fields.RequestField` from
        parameter of key/value strings AND key/filetuple. A filetuple is a
        (filename, data, MIME type) tuple where the MIME type is optional.
        For example::

            'foo': 'bar',
            'fakefile': ('foofile.txt', 'contents of foofile'),
            'realfile': ('barfile.txt', open('realfile').read()),
            'typedfile': ('bazfile.bin', open('bazfile').read(), 'image/jpeg'),
            'nonamefile': 'contents of nonamefile field',

        Field names and filenames must be unicode.

        Makes this request field into a multipart request field.

        This method overrides "Content-Disposition", "Content-Type" and
        "Content-Location" headers to the request parameter.

        :param content_type:
            The 'Content-Type' of the request body.
        :param content_location:
            The 'Content-Location' of the request body.
