I'm confused. '\040' is a regular ascii space character (040 = 32
decimal). What's unusual about either of these strings?
// This does not work (as expected)
NSLog([NSString stringWithUTF8String:[stringA UTF8String]]);
I would expect that to work (i.e. output "hello world".) What is the
actual output?
// Nor does this work
NSLog([NSString stringWithUTF8String:[[stringA
dataUsingEncoding:NSUTF8StringEncoding] bytes]]);
That is liable to misbehave or crash, since stringWithUTF8String:
expects a null-terminated string, but -bytes doesn't produce null-
terminated data.
