The current header compression draft states that header field values
are UTF-8. However, the spec says nothing about how to deal with
overlong encodings, invalid UTF-8 octet sequences or valid UTF-8
sequences that encode invalid Unicode codepoints.

I recommend stating that any of these conditions ought to result in an
error. An encoder MUST NOT output any of these; and a decoder ought to
signal a connection error if encountered.
