I'm curious: if the string is known to be 7-bit ascii, in what situation
does an 8-bit string not work where a unicde string does?

I only see one about source encodings...

Btw. while peeking around I came across the thing Bill warned for:
[NSString stringWithCString:] returns an instance of NSCFString, which
is a subclass of -- tada -- NSMutableString. This doesn't mean it _is_
mutable: I get an exception if I try. So _inheritance_ can't be used to
determine mutability. Does anyone know off hand what can?
