SharpReader is a 3 panel RSS viewer for Windows with filtering capability. Note that this requires that you have .NET runtime support installed.
I'm still looking for a Japanese RSS reader to show to my colleagues. It subscribed to a few Japanese feeds which seemed to work. See this Image of SharpReader with Japanese RSS feeds The filtering also works
except that the Filter text area needs to have the same font as font
selected in the options so is currently suffering from mojibake.
