Yeah, I saw it, and I'm convince that no matter how smart we do it, it will end up being almost enough, and take up just as much space to code. Our current fear for ASCII in the kernel dates from when space was tight on PDP/11s for heavens sake, it is NOT rational in any way. Look at sysctl to understand where I'm coming from.
