While playing around with RSS feeds on Stack Overflow I came across a bug when trying to get a feed for the
If you go to http://stackoverflow.com/feeds/tag?tagnames=c%23&sort=newest you will see that it takes you to the feed for the
c tag instead. Using the shorthand http://stackoverflow.com/feeds/tag/c%23 responds in the same way.
The first feed URL came from the bottom of C# tagged questions page.
EDIT: If you try to escape the % as well it will work for the long URL but not the short. http://stackoverflow.com/feeds/tag?tagnames=c%2523&sort=newest pulls up the
c# tag feed, but http://stackoverflow.com/feeds/tag/c%2523 returns a blank page.
EDIT 2: It appears to be in Chrome only. Just tested other browsers (Firefox, Safari, IE8, Opera) and they work as expected.
