michael@0 10 unescape( string )
michael@0 11
michael@0 12 Description:
michael@0 13 This tests the cases where one of the four characters following "%u" is
michael@0 14 not a hexidecimal character, or one of the two characters following "%"
michael@0 15 or "%u" is not a hexidecimal character.
michael@0 16
michael@0 17 The unescape function computes a new version of a string value in which
michael@0 18 each escape sequences of the sort that might be introduced by the escape
michael@0 19 function is replaced with the character that it represents.
michael@0 20
michael@0 21 When the unescape function is called with one argument string, the
michael@0 22 following steps are taken:
michael@0 23
michael@0 24 1. Call ToString(string).
michael@0 25 2. Compute the number of characters in Result(1).
michael@0 26 3. Let R be the empty string.
michael@0 27 4. Let k be 0.
michael@0 28 5. If k equals Result(2), return R.
michael@0 29 6. Let c be the character at position k within Result(1).
michael@0 30 7. If c is not %, go to step 18.
michael@0 31 8. If k is greater than Result(2)-6, go to step 14.
michael@0 32 9. If the character at position k+1 within result(1) is not u, go to step
michael@0 33 14.
michael@0 34 10. If the four characters at positions k+2, k+3, k+4, and k+5 within
michael@0 35 Result(1) are not all hexadecimal digits, go to step 14.
michael@0 36 11. Let c be the character whose Unicode encoding is the integer represented
michael@0 37 by the four hexadecimal digits at positions k+2, k+3, k+4, and k+5
michael@0 38 within Result(1).
michael@0 39 12. Increase k by 5.
michael@0 40 13. Go to step 18.
michael@0 41 14. If k is greater than Result(2)-3, go to step 18.
michael@0 42 15. If the two characters at positions k+1 and k+2 within Result(1) are not
michael@0 43 both hexadecimal digits, go to step 18.
michael@0 44 16. Let c be the character whose Unicode encoding is the integer represented
michael@0 45 by two zeroes plus the two hexadecimal digits at positions k+1 and k+2
michael@0 46 within Result(1).
michael@0 47 17. Increase k by 2.
michael@0 48 18. Let R be a new string value computed by concatenating the previous value
michael@0 49 of R and c.
michael@0 50 19. Increase k by 1.
michael@0 51 20. Go to step 5.
