The hash value of a character sequence is defined to be the hash of its unicode code points, according to #lookup3ycs(int[] k,int offset,int length,int initval)

If you know the number of code points in the CharSequence , you can generate the same hash as the original lookup3 via lookup3ycs(s, start, end, initval+(numCodePoints<<2))
