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. Get the character at position k within Result(1). + 7. If Result(6) is one of the 69 nonblank ASCII characters + ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz + 0123456789 @*_+-./, go to step 14. + 8. Compute the 16-bit unsigned integer that is the Unicode character + encoding of Result(6). + 9. If Result(8), is less than 256, go to step 12. + 10. Let S be a string containing six characters "%uwxyz" where wxyz are + four hexadecimal digits encoding the value of Result(8). + 11. Go to step 15. + 12. Let S be a string containing three characters "%xy" where xy are two + hexadecimal digits encoding the value of Result(8). + 13. Go to step 15. + 14. Let S be a string containing the single character Result(6). + 15. Let R be a new string value computed by concatenating the previous value + of R and S. + 16. Increase k by 1. + 17.
