Call ToString(string). + 2. Compute the number of characters in Result(1). + 3. Let R be the empty string. + 4. Let k be 0. + 5. If k equals Result(2), return R. + 6. Let c be the character at position k within Result(1). + 7. If c is not %, go to step 18. + 8. If k is greater than Result(2)-6, go to step 14. + 9. If the character at position k+1 within result(1) is not u, go to step + 14. + 10. If the four characters at positions k+2, k+3, k+4, and k+5 within + Result(1) are not all hexadecimal digits, go to step 14. + 11. Let c be the character whose Unicode encoding is the integer represented + by the four hexadecimal digits at positions k+2, k+3, k+4, and k+5 + within Result(1). + 12. Increase k by 5. + 13. Go to step 18. + 14. If k is greater than Result(2)-3, go to step 18. + 15. If the two characters at positions k+1 and k+2 within Result(1) are not + both hexadecimal digits, go to step 18. + 16. Let c be the character whose Unicode encoding is the integer represented + by two zeroes plus the two hexadecimal digits at positions k+1 and k+2 + within Result(1). + 17. Increase k by 2. + 18. Let R be a new string value computed by concatenating the previous value + of R and c. + 19. Increase k by 1. + 20.
