       a. Let c be the code unit at index k within string.
       b. If c is %, then
          i. If k ≤ length-6 and the code unit at index k+1 within string is u
             and the four code units at indices k+2, k+3, k+4, and k+5 within
             string are all hexadecimal digits, then
             1. Let c be the code unit whose value is the integer represented
                by the four hexadecimal digits at indices k+2, k+3, k+4, and
                k+5 within string.
             2. Increase k by 5.
