right. I am using a gnome-terminal (v3.18.3)
on an up-to-date Ubuntu 16.04.

I am usually inside byobu/tmux, but the issues remain the same,
inside or outside byobu, so it seem really to be somethig
to tackle in gnome-terminal (which AFAIR, is essentially a very
tweaked (or layer over) x-term).

Valuable notes, thanks.
I would like to configure it from Vim,
if any idea or info comes to mind,
please drop a line here.
I'll do the same.

You did not state what are you using exactly, this is essential to
answer a question. If you are using Vim in a terminal emulator then
you may need to ask *in terminal emulator’s mailing list* first
because Vim has no choice, but to swallow whatever terminal emulator
throws at it. Ability to get help here in this case would depend on
whether there are enough advanced users of your terminal emulator
reading vim_use.

Note that normally terminal emulators have a setting allowing to use
either `` or the eighth bit for `
