Sorry, thanks for re-pinging this, it fell off my radar. Yes, I have heard back from WG14 but there was not really a consensus position (which means we'd need to write a paper if we want a more detailed answer from the committee). The direction things seemed to be heading, but we did not confirm, is that the library impacts the value of `__STDC_ISO_10646__` and so we don't have a way to set what this should expand to within the compiler.
