Thread:Talk:Universal Language Selector/Font Problem in Tamil Wiki/reply (5)

Hello, I've read the whole page (not the Tamil talk, sorry) and in short it says 1) everyone could read everything before, 2) now nobody can't read anything; but I don't understand one thing: you seem to assume that everyone has the needed font installed locally. What's this system font you're talking about, what operating systems have it/them installed? If everyone has it/them, how comes you have e.g. a "font help" link in the sidebar?
