Plan 9 has had native Unicode support pretty much since day one (circa
1989).  E.g.:

	int Δt = time(0) - αρχη;

is valid C. There have been no issues with people using visually
similar characters in a way that causes confusion.  Mind you, Plan 9
users tend to be militant minimalists, so nobody uses this feature
just because they can. 

Sun's Fortress language also fully integrates Unicode into its
grammar.
