    '''':param match: A match object such that \'&\'+match.group(1)\';\' is the entity.
    :param exceptions: A list of entities to not convert (Each entry is the name of the entity, for e.g. \'apos\' or \'#1234\'
    :param encoding: The encoding to use to decode numeric entities between 128 and 256.
    If None, the Unicode UCS encoding is used. A common encoding is cp1252.
    :param result_exceptions: A mapping of characters to entities. If the result
    is in result_exceptions, result_exception[result] is returned instead.
    Convenient way to specify exception for things like < or > that can be
    specified by various actual entities.'
