I think font selection is important to make it a fair comparison. For each language, the minimal resolution "pixel font" that still works should be used. (E.g. Chinese hanzi are going to require more resolution than the latin alphabet.) The fonts used in Minecraft might be a good start. However, once you do that, it probably doesn't make sense to only count the "on" pixels. Because in a minimal font, "off" pixels will probably contribute as much information as "on" pixels. So you should just count the total number of pixels required to render the piece of text.
