      This function is designed for data frames.
  
      If ``data`` is a :class:`str`, return ``OP_TEXT`` and a :class:`bytes`
      object encoding ``data`` in UTF-8.
  
      If ``data`` is a bytes-like object, return ``OP_BINARY`` and a bytes-like
      object.
  
      Raise :exc:`TypeError` for other inputs.
