Loading randomized text to swf

I had a very simple idea of loading random words from external text file to Adobe Flash Pro CS6 and creating a small size .swf that can be converted to screensaver and works both on Windows and OS. Text must scroll down as it fills the screen, and it must contain Unicode characters. I tried loading randomized text with LoadVars but I couldn't get it to display right characters. With as3 it’s simple to load text with html formatting and even CSS but then I got stuck at scrolling and randomization. Most definitely the problem is approached from the wrong direction but since it's a long shot anyway, does anyone have any suggestions?
