Generating proper URLs even when you have &, " ", etc, as part of the title

When creating a page, and having latin characters such as &, " ", etc, a URL is generated like this: http://www.gigaspaces.com/wiki/pages/viewpage.action?pageId=8375 and not http://www.gigaspaces.com/wiki/display/GS/Welcome+to+GigaSpaces.

This is improtant because we tend to use & a lot in page titles since some of our page titles are very long and this helps makes them shorter and nicer.
