This class is accessible through :py:class:`PdfReader.metadata`. All text properties of the document metadata have *two* properties, e.g. author and author_raw. The non-raw property will always return a ``TextStringObject``, making it ideal for a case where the metadata is being displayed. The raw property can sometimes return a ``ByteStringObject``, if pypdf was unable to decode the string's text encoding; this requires additional safety in the caller and therefore is not as commonly accessed.
