nit: I'd get rid of these in favor of std::end(hashes) - std::begin(hashes) now.

We can do that in a follow up.

 
     size_t current = 0;
     const uint32_t* data = nullptr;
     size_t sizeInBytes = sizeof(UChar) * str.length();
     data = reinterpret_cast<const uint32_t*>(str.characters16());
     for (size_t i = 0; i < sizeInBytes / 4; i += 4) {
         uint32_t v = data[i];
         uint64_t xi = v * randomOdd[current] & 0x7FFFFFFF;
         hashes[current] = (hashes[current] + zi[current] * xi) % prime[current];
         zi[current] = (zi[current] * random[current]) % prime[current];
