Reverse and partial line feeds
RI (U+008D REVERSE LINE FEED, ISO/IEC 6429 8D, decimal 141) is used to move the printing position back one line (by reverse feeding the paper, or by moving a display cursor up one line) so that other characters may be printed over existing text. This may be done to make them bolder, or to add underlines, strike-throughs or other characters such as diacritics. The reverse line feed was called a line starve – a pun on line feed – in the Hacker's Dictionary.
