I don't know why it isn't working for you. My vim 8.1.685 running
on Ubuntu 16.04.5 LTS and displaying to GNOME Terminal 2.32.0 over
an ssh connection works just fine. I set 'listchars' like this in
my vimrc:

:set listchars+=tab:▸-

where I copied and pasted that triangle from your email.

I also diffed your Ubuntu vim version info against mine and I didn't
see anything obvious to me that would cause such a problem.

(To diff the two "vim --version" outputs, I put them into two
side-by-side buffers (vertically split). Then in each buffer,
I visually-selected the block of features and executed on them:

:s/\_s\+/\r/g
:sort /^./

Finally, I executed:

:windo diffthis

That makes the differences pretty easy to see.)

Could this be a locale issue? Mine is this:

LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE=C
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
