elisp: Active Display Table

 
 37.22.3 Active Display Table
 ----------------------------
 
 Each window can specify a display table, and so can each buffer.  The
 window’s display table, if there is one, takes precedence over the
 buffer’s display table.  If neither exists, Emacs tries to use the
 standard display table; if that is ‘nil’, Emacs uses the usual character
 display conventions (Usual Display).
 
    Note that display tables affect how the mode line is displayed, so if
 you want to force redisplay of the mode line using a new display table,
 call ‘force-mode-line-update’ (Mode Line Format).
 
  -- Function: window-display-table &optional window
      This function returns WINDOW’s display table, or ‘nil’ if there is
      none.  The default for WINDOW is the selected window.
 
  -- Function: set-window-display-table window table
      This function sets the display table of WINDOW to TABLE.  The
      argument TABLE should be either a display table or ‘nil’.
 
  -- Variable: buffer-display-table
      This variable is automatically buffer-local in all buffers; its
      value specifies the buffer’s display table.  If it is ‘nil’, there
      is no buffer display table.
 
  -- Variable: standard-display-table
      The value of this variable is the standard display table, which is
      used when Emacs is displaying a buffer in a window with neither a
      window display table nor a buffer display table defined, or when
      Emacs is outputting text to the standard output or error streams.
      Although its default is typically ‘nil’, in an interactive session
      if the terminal cannot display curved quotes, its default maps
      curved quotes to ASCII approximations.  Keys in
      Documentation.
 
    The ‘disp-table’ library defines several functions for changing the
 standard display table.
