Comment (by Kronuz):

 These are my timings after adding the `std::string s` and appending to it:

 {{{
 Run on (4 X 3000 MHz CPU s)
 CPU Caches:
   L1 Data 32K (x2)
   L1 Instruction 32K (x2)
   L2 Unified 262K (x2)
   L3 Unified 4194K (x1)

 Benchmark                          Time           CPU Iterations

 BM_EncodeLength_Optimized       1510 ns       1507 ns     591061
