While I was watching the Mario Maker Direct, I noticed that the text now had lowercase. So I studied the UK version to get all the characters (except for 'f').
Update (06/25): I found 'f' in some gameplay footage that was released
Update (07/01): The 7 in the promotional art from SMM1 is now the official 7 for the font. Beginning work on accents.
Update (07/26): Updated a, e, f, j, and z. Also fixed the 7. This is probably the most accurate it can get for now.This is a clone of Super Mario Maker Extended
