1.11 + File Name: 15.1.2.5-3.js
1.12 + ECMA Section: 15.1.2.5 Function properties of the global object
1.13 + unescape( string )
1.14 +
1.15 + Description:
1.16 + This tests the cases where one of the four characters following "%u" is
1.17 + not a hexidecimal character, or one of the two characters following "%"
1.18 + or "%u" is not a hexidecimal character.
1.19 +
1.20 + The unescape function computes a new version of a string value in which
1.21 + each escape sequences of the sort that might be introduced by the escape
1.22 + function is replaced with the character that it represents.
1.23 +
1.24 + When the unescape function is called with one argument string, the
1.25 + following steps are taken:
1.26 +
1.27 + 1. Call ToString(string).
1.28 + 2. Compute the number of characters in Result(1).
1.29 + 3. Let R be the empty string.
1.30 + 4. Let k be 0.
1.31 + 5. If k equals Result(2), return R.
1.32 + 6. Let c be the character at position k within Result(1).
1.33 + 7. If c is not %, go to step 18.
1.34 + 8. If k is greater than Result(2)-6, go to step 14.
1.35 + 9. If the character at position k+1 within result(1) is not u, go to step
1.36 + 14.
1.37 + 10. If the four characters at positions k+2, k+3, k+4, and k+5 within
1.38 + Result(1) are not all hexadecimal digits, go to step 14.
1.39 + 11. Let c be the character whose Unicode encoding is the integer represented
1.40 + by the four hexadecimal digits at positions k+2, k+3, k+4, and k+5
1.41 + within Result(1).
1.42 + 12. Increase k by 5.
1.43 + 13. Go to step 18.
1.44 + 14. If k is greater than Result(2)-3, go to step 18.
1.45 + 15. If the two characters at positions k+1 and k+2 within Result(1) are not
1.46 + both hexadecimal digits, go to step 18.
1.47 + 16. Let c be the character whose Unicode encoding is the integer represented
1.48 + by two zeroes plus the two hexadecimal digits at positions k+1 and k+2
1.49 + within Result(1).
1.50 + 17. Increase k by 2.
1.51 + 18. Let R be a new string value computed by concatenating the previous value
1.52 + of R and c.
1.53 + 19. Increase k by 1.
1.54 + 20. Go to step 5.
