Character used when Allegro cannot find a glyph.
When Allegro cannot find a glyph it needs in a font, it will instead
output the character given in allegro_404_char. By default, this is set to
the caret symbol, `^', but you can change this global to use any other
character instead. Example:
/* Show unknown glyphs with an asterisk. */
allegro_404_char = '*';
