[SOLVED] Nerd fonts, ssh and tmux conflicting

Hello, I have a new install of arch which I'm planning to use mainly over ssh.

I have set up tmux, starship and neovim. When I launch them locally (using a window manager) they
work properly and show the appropriate nerd font symbols, both within tmux and out

I also have set up an ssh config entry so that when I login to the machine using ssh it automatically
starts and joins a tmux session

Host tmx-arch
  IdentitiesOnly yes
  RemoteCommand tmux new -A -s tp
  RequestTTY yes
  EscapeChar none

I have used without issue similar configurations (to connect to an Ubuntu VM as well as an Ubuntu
laptop) and it always worked without creating issues, however when I run "ssh tmx-arch" it log into
tmux but where I'd expect symbols to appear I just get placeholders (an underscore, not a typical
tofu if it has any significance)

Weirdly enough connecting through ssh and only then spawning a tmux session does not present
the same issue

Does anyone have any idea what the problem might be?
Thanks for your help, I tried to look around but couldn't find any similar issues

This will depend on something in your environment, I'd compare the environment of (likely) the tmux but also the shell process between the two invocations.

tr '\0' '\n' < /proc/$PID/environ

Edit: and I'd especially look for the locale variables…

Re: [SOLVED] Nerd fonts, ssh and tmux conflicting

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

The obvious one is the starship stuff… (and generally OMZ exists merely to break zsh in various funny ways)

Edit:

where I'd expect symbols to appear I just get placeholders (an underscore, not a typical tofu if it has any significance)

itr I assume "where I'd expect" /is/ the starship stuff?

Re: [SOLVED] Nerd fonts, ssh and tmux conflicting

Fixed the quote, didn't realize there was a separate formatting for code

The starship prompt is one such case but neovim is also not showing them and I've tested with the nerdfont script
and that too works in one case and breaks in the other.

I tried also by removing the zsh customizations and the problem persists (tested with the script and nvim)

Do you have comparative screenshots for the "underscore, not a typical tofu"?

I'm leaving this here just in case anyone's curious https://imgur.com/a/BLpLHIW

Thanks for noticing the missing paths. Not sure what the specific cause was but it's something
due to the ssh command not executing in a login shell and so not sourcing /etc/profile

I fixed it by executing the command through a login shell instead:

RemoteCommand exec $SHELL -lc "tmux new -A -s win-tp"
