Answered my own question. Here's the working line to output to an xterm compatible title from inside tmux: > printf '\ePtmux;\e\e]2;%s\e\e\\' "$*"
Part of the issue was the Mac Terminal's built-in update_terminal_cwd function.
This sets the URL for the Terminal application's titlebar. It was (incorrectly)
trying to set the title from inside tmux and breaking my escape sequence above.
I redefined the function via .bash_profile to handle tmux:
> update_terminal_cwd () { # Update to Mac terminal built-in function for
> setting title bar URL - handles tmux correctly
> local SEARCH=' ';
> local REPLACE='%20';
> local PWD_URL="file://$(HOSTNAME)${PWD//${SEARCH}/${REPLACE}}";
> if [[ -z ${TMUX} ]]; then # Not in tmux
> printf '\e]7;%s\e\\' "${PWD_URL}"
> else # In tmux
> printf '\ePtmux;\e\e]7;%s\e\\' "${PWD_URL}"
> fi

Hopefully this will save the next user some time.
