Binary access to character strings

[chrome]

The problem I got is I'm trying to access the binary for character strings. It for a fitness function for a genetic algorithm.

I have x,y positions, and need to access their binary to create child x,y positions.

e.g.

two coords p1 and p2;

---p1------------------------p2
---x---------y-------------x----------y
--00-011---00-100-----01-000----00-001

I need to acces the binary to splice them into the new coords of

---new-p1----------------new-p2
---x----------y------------x----------y
--00-000---00-001-----01-011---00-100

Can anyone suggest binary function avaliable, or methods to access character string binary

Thanks
