(a) Why not? (Okay, in the case of newline, there is a good reason why
not. But for others?) People wouldn't normally use them, no, but as
the original message (probably inadvertently) pointed out, not all
usernames belong to people.
(b) For whose value of "unprintable"? ASCII? ISO 8859? JIS
whatever-it-is? (Escape-sequence character set shifts in usernames?)
