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. See Display Tables.
