1)

   qdtext         = WSP / %x21 / %x23-5B / %x5D-7E / obs-text
                  ; WSP / <VCHAR except DQUOTE and "\"> / obs-text
   obs-text       = %x80-FF

2)

What's the problem with obs-text? It doesn't contain controls...

3)

It seems to me that the purpose of quoted-text is to allow any character 
in qdtext, plus DQUOTE and "\", which would make it

quoted-text = qdtext / DQUOTE / "\"

While we're at it, we probably should rename it to quoted-char, and also 
add a short statement what the semantics of a quoted-pair is.
