Mapping of letters to positions in alphabet

[gawalione]

Hi there,
i want to add some support for czech, slovak and polish to my multi cache addon.

The german wikipedia lists the following alphabets for these languages:
A, (Á), B, C, Č, D, (Ď), E, (É), (Ě), F, G, H, Ch, I, (Í), J, K, L, M, N, (Ň), O, (Ó), P, Q, R, Ř, S, Š, T, (Ť), U, (Ú), (Ů), V, W, X, Y, (Ý), Z, Ž.
A, Á, Ä, B, C, Č, D, Ď, Dz, Dž, E, É, F, G, H, Ch, I, Í, J, K, L, Ĺ, Ľ, M, N, Ň, O, Ó, Ô, P, Q, R, Ŕ, S, Š, T, Ť, U, Ú, V, W, X, Y, Ý, Z, Ž.
A, Ą, B, C, Ć, D, E, Ę, F, G, H, I, J, K, L, Ł, M, N, Ń, O, Ó, P, Q, R, S, Ś, T, U, V, W, X, Y, Z, Ź, Ż.

Now i'm wondering, what the most used mappings from the letters to their values are in the different languages.

In German its like this: A=1, Ä=33, B=2, C=3, D=4...

Can anybody help?
