This is a clone of SMDS ES/FR/DE/ITThis has more letters than the original version that weren't originally in the game. I'd recommend you choose this one, as it has more stuff.

I literally had to rip the sprites myself because the rip on TSR is missing... well, EVERYTHING.
Edit: holy crap i didn't know BlueYoshiN64 was already doing this so i added Solid to the name
Buttons and console names for retro tracks are in the High Private Use Surrogates (starting from U+DB80). More "squished" characters (used for Bowser's Castle 2 in french and maybe other circuits because normal characters don't fit in the menu) are in the Halfwidth and Fullwidth blocks (to add later).
Recreation of the 6px pixel font used in Nintendo's "Super Mario Kart" (1992) on the SNES. In the game, the font has a 2px spacing to account for the outline. In this recreation, I opted to just go for a 1px spacing - if you do use it outlined, make sure to add the extra pixel for authenticity.
Update Sept. 2019: added ":" and "," and fixed incorrect "Q", "V", "(" and ")"
