You might be interested in the Flash module which can load up specially packaged unicode font files. This means that you can embed every kind of unicode font in a Flash activity and don't require your site visitors to have the font to display the font properly. See for example here :

There are some documents on my site http://jamiep.org about how to set up these activities.
