hi there, been having this problem for some time now.
if the title of the article contains " ) xyz" the link in the rss feed gets bugged.
i resubscribed, but that didnt fix the problem.
here an example screenshot:
this way you will always get "Page not found" when you open the bugged link.
would be great, if you could fix this, so i dont have to go to the link manually everytime.
