When using XS from a C++ app that uses UTF16 internally (multi-platform), what's the right way to send strings back and forth?

I can transcode to UTF8 and newSVpv( ) them, but do I then need to SvUTF8_on( ) every one of those? Or does perl figure it out on its own?

What about XPUSHp( ) and POPp( )? Do I need to test for UTF8 on each of those?

Is giving the interpreter -Mutf8 on startup the Right Thing to do?
