docs: Curses does define constants for symbols (e.g. curses.ACS_BULLET).
          However, they rely on using the curses.addch() function, which has been
          found to be buggy and a general PITA to work with. By defining them as
          unicode points they can be added via the more reliable curses.addstr().
