    non-ASCII values, like file names. This follows RFC 2388 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.

    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``.

        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.

        Helper function to format and quote a single header.

        Useful for single headers that are composed of multiple items. E.g.,
        'Content-Disposition' fields.

        :param header_parts:
            A sequence of (k, v) tuples or a :class:`dict` of (k, v) to format
            as `k1="v1"; k2="v2"; ...`.
