1) we could say that they're prohibited

2) we could define a use for them in RFCs and require their support

My point with these and the control codes was that the doc had a small 
oversight - it should say "printable UTF8 excluding Private Use, and a 
fixed subset of control chars", not merely UTF8.

Fixing this is simple and probably easy to reach consensus on quickly, 
it's just that the current doc is insufficient by just referring to UTF8 
without any caveats.
