docs: A ``dict`` with the encoding chars of the :class:`Element <hl7apy.core.Element>`.
          If the :class:`Element <hl7apy.core.Element>` has a parent it is the parent's
          ``encoding_chars`` otherwise the ones returned by
          :func:`get_default_encoding_chars <hl7apy.get_default_encoding_chars>`
          The structure of the ``dict`` is:
  
          .. code-block:: python
  
              {'SEGMENT' : '\\r',
              'GROUP': '\\r',
              'FIELD' : '|',
              'COMPONENT' : '^',
              'SUBCOMPONENT' : '&',
              'REPETITION' : '~',
              'ESCAPE' : '\\'}
