Given an arbitrary set of letters
String range = "0123456789abcdefghijklmnopABCD#";
I am looking for 2 methods to encode/decode from long <-> String
String s = encode( range, l );
and
long l = decode( range, s );
So decode(range, encode(range, 123456789L)) == 123456789L
And if range is "0123456789" thats the usual way of encoding.
