Outside ^H and inside ^? sounds fine but it's bad if both backspace and
delete generate the same sequence because then the applications can't
distinguish them, right? For me in xterm the delete key generates
"^[[3~" which is what
infocmp xterm-256color | grep 'kbs\|kdch1'
would suggest. Do you happen to have a misconfigured iterm2? [1]
suggests that there is a "Delete sends Control-H" option. Try disabling
that.

I'm not familiar with emacs so I have not sure what went wrong there.
I think if whatever key you get for backspace matches up with what stty
reports for erase then that's rather an emacs bug if it can't parse it.
In any case try tweaking your emacs settings[2].

Is this inside or outside tmux? If this is reported from inside then
something is wrong. Do you have any stty overrides in one of your shell
rc files somewhere?
