Re: function to decode url percent encoding

[Xah Lee]

did some more testing about this.

the issue first of all seems to be that what characters should be
percent encoded.

i did some testing with browsers, IE, Firefox, Safari, Opera, all
behaved a bit differently in what they think should be percent
encoded.

Summary

Here's some summary of the behavior as it appears from above tests:

    * Firefox (v 3.6.3), is the most aggressive in turning characters
in url into the percent encoded form.
    * Google Chrome (4.1.249.1064 (45376)) will change unicode chars
into percent encoded form, but not parenthesis chars.
    * Safari (4.0.5 (531.22.7)) is better, in that it simply show the
characters as is, as much as it can.
    * Opera (v 10.10, build 1893) is the best, it shows unicode and
paren and en-dash as is.
    * IE (8.0.6001.18904), seems to take the approach that it doesn't
do anything to the url. Whatever you pasted in, remain unchanged
