Using win7 but not ultimate, interesting thing: when i change my settings for unicode programs to japanese, i get jibberish text, but when i clean the screen with RMB, then i press LMB to bring back the frame and voila: the text is displayed correctly and ITH's TinkerBell2 thread gets updated...
update your ITH with ITH_Updater.exe, then you can use TinkerBell2 thread.
or if you don't like/trust the updater, download the updated files from here: ITH3
