In addition to what might be useful/ necessary for readers of
5335bis, in retrospect, we ought to have a prominent comment in
one of the more generic i18n documents that highlights the fact
that the, once one moves beyond ASCII, length-in-characters and
length-in-octets, can no longer be assumed to be the same. When
one is actually talking about storage length,
length-in-characters should be prohibited from our vocabulary
going forward. That would actually make an interesting
extension to a nits-checker if someone could figure out how to
do it or, at least, a flag to the RFC Editor about something
they should watch out for.
