Hi Kim. FeedBeast supports standard Unicode characters, and that should include Russian characters as well, but you may have to install some "language packs" on your computer, if you're running XP. To be honest I'm not entirely sure how that works, but if you run Vista this should be automatic.
I suggest looking into the language packs thing. All I know is that on XP, FeedBeast will not show for example chinese characters (and therefore I assume Russian as well), but on Vista it does fine. So it's not the fault of FeedBeast so much as the operating system. I was told the answer was language packs, but did not look into it any further.
Do let me know if you discover anything.
