Call for review: SSH IUTF8 terminal mode

[Simon Tatham <[e-mail]>]

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
