I am a graphic designer and I try to only have fonts installed that I'm using for a project, or for general use. I always end up uninstalling all these Thai, Chinese, Indian and other typefaces that install with Ubuntu. However, even though I can't read these alphabets, I do prefer to see them when displayed on a website (e.g. Wikipedia) than to just see boxes.
Are there one or two fonts that will cover most non-Roman alphabets? I don't mind having a couple installed.
