A bunch of new character ideas:

A: Triple-V capital

B: 10 (if you want to know the purpose of this character go see 0-9)

C-G: Tetrominoes (4-connected squares)

H-S: Pentominoes (5-connected squares)

T: Filled Triangle

U: Filled Square

V: Filled in Pentagon

W: Not Filled in Triangle

X: Not Filled in Square

Y: Not Filled in Pentagon

Z: Diagonal (Placeholder)

0-9: 10-19 

(efficient as one character and would help a lot if it were one character because it saves up a lot of my time trying to code a counter to give me one extra slot so that I can put the extra digit in the slot and code the extra digit to go in the slot)

a: Triple-V lowercase

b-i: 30-100 (multiples of 10)
