38.17 Display Tables

You can use the display table feature to control how all possible character codes display on the screen. This is useful for displaying European languages that have letters not in the ASCII character set.

The display table maps each character code into a sequence of glyphs, each glyph being a graphic that takes up one character position on the screen. You can also define how to display each glyph on your terminal, using the glyph table.

Display tables affect how the mode line is displayed; if you want to force redisplay of the mode line using a new display table, call force-mode-line-update (see section 23.3 Mode Line Format).

38.17.2 Active Display Table  How Emacs selects a display table to use.
