--- Comment #15 from Marco Trevisan <mail at 3v1n0.net> ---
Hey,

Another attempt here at
https://github.com/openssh/openssh-portable/pull/452

Sadly this change also required some client changes (mostly "cosmetic")
as the handling of the instructions was not supported as utf-8 text (as
it should be according to the spec).

I've also added a setting to control this and in order to continue
supporting legacy clients without requiring any change on their side,
the device `pam-legacy-instructions` (e.g.
KbdInteractiveDevices=pam-legacy-instructions) can be used to make new
daemons to act as before.

Commits should explain better the rationale.
