On Mac OS X, the Character Viewer (equivalent to Character Map on Ubuntu) has a feature where, when looking at a certain character, it can show a list of all fonts that contain that character. Is there something equivalent on Ubuntu?
The use case is that, for instance, I could click on a Kannada character and see all fonts that cover that character (and presumably, the rest of the Kannada language range).
Edit: Just for an idea of what I mean, here's a screenshot of Character Viewer on Mac OS X 10.6. The "Containing selected character" is near the bottom of the screen. I seem to remember that this part of the interface was better in 10.5 or 10.4, actually.
