I believe solving the header field encoding problem would be great; in 
particular with some people trying to move all metadata into header fields.

As far as I can tell, the only widely used header field that *does* 
require non-ASCII is Content-Disposition, for which a non-lossy 
transformation is available (see 5987/6266), although some older UAs do 
not get that.
