  Enable unicode box-drawing characters for map and table display.

  Type:    boolean (on/off)

  When on, maps use box-drawing characters for borders and the
  options table uses a formatted grid. When off, ASCII fallback
  characters are used instead (. and : for maps, + and | for tables).

  Usage: option unicode off
         option unicode on
