Wait! Percent-Encoded?

If we can't transport the field value, we really shouldn't alter it in 
a way the recipient isn't going to understand (reminder: percent 
encoding isn't really a feature of field values!).

SO I think it would be much better to reject these, optimally on the 
HTTP/2 layer as well.
