elisp: Character Display

 
 37.22 Character Display
 =======================
 
 This section describes how characters are actually displayed by Emacs.
 Typically, a character is displayed as a “glyph” (a graphical symbol
 which occupies one character position on the screen), whose appearance
 corresponds to the character itself.  For example, the character ‘a’
 (character code 97) is displayed as ‘a’.  Some characters, however, are
 displayed specially.  For example, the formfeed character (character
 code 12) is usually displayed as a sequence of two glyphs, ‘^L’, while
 the newline character (character code 10) starts a new screen line.
 
    You can modify how each character is displayed by defining a “display
 table”, which maps each character code into a sequence of glyphs.
