       a. Let c be the code unit at index k within string.
       b. If c is %, then
          [...]
          ii. Else if k ≤ length-3 and the two code units at indices k+1 and
              k+2 within string are both hexadecimal digits, then
              1. Let c be the code unit whose value is the integer represented
                 by two zeroes plus the two hexadecimal digits at indices k+1
                 and k+2 within string.
              2. Increase k by 2.
