Call for review: SSH IUTF8 terminal mode

I'm trying to get an RFC published that standardises the use of code 42
for the IUTF8 terminal mode bit.

This has been suggested on this list more than once: in the mailing list
archives at

  ftp://ftp.ietf.org/ietf-mail-archive/secsh/

I can find discussion started by Colin Watson on 2005-12-31, and by
David Madore on 2013-03-29. Both suggestions allocated the same number
(42) for the flag.

Moreover, Fedora's package of OpenSSH already seems to be running with a
downstream patch implementing IUTF8 under that number. For example, I
just found

  https://dl.fedoraproject.org/pub/fedora/linux/updates/23/SRPMS/o/openssh-7.2p2-3.fc23.src.rpm

which contains a patch file openssh-7.1p1-iutf8.patch implementing it. I
also know tha MouSSH has a development branch containing the same
feature.

So I'd like to bless that existing consensus and practice by turning
this Internet-Draft into an RFC:

  https://datatracker.ietf.org/doc/draft-sgtatham-secsh-iutf8

and am calling for reviews. If anyone has any review comments or
(hopefully not) objections, please send them along!

Cheers,
Simon
