Questionmark in urls

Hi,

If I want to save a URL which contains a Questionmark (?) in my created Event, the link does not work anymore, when I click on it. The Event URL is Properly displayed, but when I click on it, and it opens Safari to get to the URL, it converts the ? into %3F.

Is this a iCal bug, or a Safari bug or something Systemwide? Does it maybe has to do with my setup system language (which is german)?

A lot of php sites uses ? in their urls and if I save them in my calendar, they are always useless. I always have to copy paste the URL out of the event into my browser to see the url.

Here is a screenshot, because maybe its easier to understand, what my problem is. As you can see, the URL in the calender box is formatted right (with the ... index.php?mode ...). When I copy paste the URL from cal back to a browser, it works perfectly. But when I click on the URL to let the browser open the site automatically, it changes the URL (... index.php%3Fmode ...) and thus the Page can't be found.

Does anyone know a solution to this problem, or is it a known bug? Do others have the same problem (though I searched for this topic, I couldn't find any posts, so I don't know, if its something with my mac, or that just other people doesn't save URLs in their cal events)?

Thank you!
