Below is an overview of the fields in the sfeed(5) TAB-separated feed f [08/17]

     For the fields title, id and author each whitespace character is replaced
     by a SPACE character.  Control characters are removed.

     The content field can contain newlines and these are escaped.  TABs,
     newlines and '\' are escaped with '\', so it becomes: '\t', '\n' and
