I think you want bash's "preexec" hook, although I am not sure exactly how to use it. That is how iTerm2 sends its "before command" escape sequences and whatnot.
As far as doing it in tmux goes I don't really know how screen's implementation works but I don't want to encode special stuff for bash, zsh etc in tmux so I'm thinking of a couple of possibilities. Perhaps an option to say "when you see X escape sequence, match the rest of this line against this regex and use the first submatch". Or it might be more flexible just to store the rest of the line in a variable rather than actually renaming the window, then you could put it in window-status-format or status-left or automatic-rename-format or anything else with whatever transformations you like. But if you can do it with the existing \033k then it hardly seems necessary.
