Not supporting Unicode often drive me crazy/sad, especially for a diff/patch tool.

Having control makes me happy/sane. Having unicode set to (on|off) does not affect either diff/patch.

It doesn't actually change the charset, it changes the behaviour of a few libc functions and other things that use it (like perl). Sane programs ignore libc locales, as you do not want the behaviour of your program changing randomly based on some environment variables, that way madness lies.
