Can I configure the tmux startup command?

[qmacro]

My CLI environment is a shell inside a container, and I need to start tmux with the -u option (along with ensuring TERM is set to xterm-256color) to ensure I get the full benefit of my chosen Nerd Font, including icons (if I don't use -u then all icons are just displayed as underscores).

I've looked but can't find a guide to the configuration options (apologies if I missed it!) and was wondering if I could specify what invocation sesh should use for tmux, i.e. something like:

tmux = "tmux -u"

Is that possible please?

(Thanks for the inspiration on your setup and tools and for the work on sesh!)

In the meantime, I've hacked my tmux installation:

dj@7465f9b2d4f4:~$ ls -l ~/.local/bin/ | grep tmux; cat $(which tmux)
-rwxr-xr-x 1 dj dj       25 Mar  4 16:53 tmux
drwxr-xr-x 6 dj dj    12288 Mar  4 11:52 tmux-3.5a
-rw-r--r-- 1 dj dj   715619 Mar  4 11:34 tmux-3.5a.tar.gz
-rwxr-xr-x 1 dj dj  1161728 Mar  4 11:52 tmux-binary
exec tmux-binary -u "$@"
dj@7465f9b2d4f4:~$

You may want to first try ensuring UTF-8 is properly set in your shell configuration, maybe something like this:

export LC_CTYPE=en_US.UTF-8

I'm open to allowing flags for the startup command but I want to check first that you can solve it this way.

Thanks for (a) the swift reply and (b) the suggestion, which works great!

I removed my hack (above), added export LC_CTYPE=C.utf-8 to my .bashrc and can now get icons in tmux even without the -u option.

I appreciate your patience dealing with this (ultimately non-sesh) question!

Happy to help, glad it's working for you.
