Doesn't matter.  The point is that it's easier to turn nil into
something else (e.g. "") than to turn "" into something else (e.g. nil).

Big deal: that's just an (or ... "").

And in any case no matter what the standard says, I'm pretty sure end
users would prefer to be told explicitly that a char doesn't have a name
rather than to see an empty field and wonder what that means.
