Ok, here's my list of letters. It's alot shorter than Hugomka's XD
I tryed from 0 to 600 but most didn't work so I writed down the ones necesary.

a = alt+155 alt+130
b = alt+155 alt+136
C = alt+155 alt+165
c = alt+155 alt+137
d = alt+155 alt+141
e = alt+155 alt+161
f = alt+155 alt+140
g = alt+155 alt+139
H = alt+155 alt+153
i = alt+155 alt+164
j = alt+155 alt+149
k = alt+155 alt+162
l = alt+155 alt+147
N = alt+155 alt+154
n = alt+155 alt+148
o = alt+155 alt+246
Q = alt+155 alt+225
q = alt+155 alt+151
R = alt+155 alt+133
r = alt+155 alt+163
S = alt+155 alt+160
s = alt+155 alt+150
T = alt+155 alt+131
t = alt+155 alt+385
V = alt+155 alt+132
W = alt+155 alt+390
w = alt+155 alt+152
X = alt+155 alt+145
x = alt+155 alt+658
Y = alt+155 alt+135
Z = alt+155 alt+138

0 (big zero)- alt+155 alt+223
1 - alt+155 alt+504
3 - alt+155 alt+509
7 - alt+155 alt+20 (just 20)
8 - alt+155 alt+505
~ - alt+155 alt+2586 (random made number, but it worked)
@ - alt+155 alt+73
$ - alt+155 alt+323
% - alt+a55 alt+72
= - alt+155 alt+15

The other ones I found till 600 were signs used in math or "/ \". Sometimes just chinese letters or spanish "n" (like in "senorita" lol)
And as u can see I'm missing "A, B, D, E, F, G, h, I, J, K, L, M, m, O, p, U, u, v, y, z, 2, 4, 5, 6, 9" (I don't care about the other ones XD)
