Subject: [PATCH] LibGfx: Paint replacement character, 0xFFFD, for unknown
 glyphs

Note: most systems now use a font's .notdef character for unknown
glyphs (commonly the tofu box) and reserve 0xFFFD for encoding
errors. Until Serenity supports tofu, 0xFFFD is a preferable, if
deprecated, alternative to '?' to reduce ambiguity.
