NAMEallegro_404_char - Character used when Allegro cannot find a glyph.
SYNOPSIS#include <allegro.h> extern int allegro_404_char;
DESCRIPTIONWhen 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 = '*';
