Thank you. I'm still wary about making such assumptions but I suppose we commit worse sins.

Certainly. Given that TTYs aren't typically used for displaying UTF-16, and that the Unicode-capable terminals I've tried seem to show just fine (in case someone converts the UTF-16 back to UTF-8), I think we are reasonably safe.
In any case it's no different from not being able to show an any other character.

Not unrelated at all, but by all means.
