      Args:
          raw (`str` | `bytes`): String to be processed. Byte strings will be
              interpreted as UTF-8.
          b64 (`bool`): Whether to wrap the output in a Base64 CloudFormation
              call
  
      Returns:
          :class:`troposphere.AWSHelperFn`: output to be included in a
          CloudFormation template.
