Feel free to use them! The 1 with a spur on top is used to prevent confusion. In PE digits, it's used to prevent confusion with rotated versions of it (↾, ⇂ and ⇃). When using letter digits, you should use the 1 with a spur on top to prevent confusion with lowercase l. I need someone to remix this project, to put lowercase letters into this project.
Fixes: 20 and 30 are fixed. 21 and 31 have fixed thickness of the line. 22 and 32 have better placement of the pieces. 33 doesn't have teeth, because TVOKids needs teeth when the mouth is c shaped or ɔ, not ◟ shaped. 39 has a fixed shape. 40, 41 and 50 have fixed shapes. 43 doesn't have an eye, because it doesn't fit. 54 is a †, not a T. 61 and 71 are fixed. 64 is not a €. Where are S(73)'s teeth? 79 is not a J. Fixed 83 and 87.
