{{mono|RI}} ([[Unicode|U]]+008D [[line starve|REVERSE LINE FEED]],<ref>{{cite web|url=https://www.unicode.org/charts/PDF/U0080.pdf|title=C1 Controls and Latin-1 Supplement|website=unicode.org|access-date=13 February 2016}}</ref> [[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 [[diacritic]]s.

Similarly, {{mono|PLD}} ([[Unicode|U]]+008B PARTIAL LINE FORWARD, decimal 139) and {{mono|PLU}} ([[Unicode|U]]+008C PARTIAL LINE BACKWARD, decimal 140) can be used to advance or reverse the text printing position by some fraction of the vertical line spacing (typically, half). These can be used in combination for subscripts (by advancing and then reversing) and superscripts (by reversing and then advancing), and may also be useful for printing diacritics.
