[algogeeks] Can we define a bijective function from set(strings) ------> Q?

Hi, Can we define a bijective function from set(strings) --> Q? I thought of using a polynomial function, for example: f(ANIL)=pow(31,0)*ASCII(L)+pow(31,1)*ASCII(I)+pow(31,2)*ASCII(I)+pow(31,3)*ASCII(A), In this f will be one-one from set(Strings)--->N, but I don't whether is onto or no
