Not necessarily. I have never seen a guarantee that the C++ string functions output their data in the exact format that [NSString stringWithCharacters:length:] needs as an input. As you discovered, getting UTF8 from the C++ string does give you proper data for the corresponding NSString creator method.
Assuming things are compatible between C++ and Cocoa methods usually leads to bug reports at the very least.
