I have been messing around with my tmux status bar and have behavior I don't know how to explain. I wish to clear the entire status bar and start layering it step by step, to understand what each piece does. I do the following:

enter image description here Where are the boxes with question marks coming from, and how do I get rid of them?

I have disabled all my tmux plugins and started a new session but to no avail. Any help is appreciated.

Looks to me like those are UTF-8 characters in window-status-format and window-status-current-format or window-status-separator.

  • Ugh, I had changed window-status-format and window-status-separator, but not window-status-current-format. Thank you! Will accept when timer has passed.
