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. |
