Current Behavior

https://bugs.kde.org/show_bug.cgi?id=390666
I reported it to KDE thinking it's the problem. I asked for advice concerning this bug in KDE irc.
I type cat in konsole and press c-h, it worked and show ^H.
I type stty -a in konsole and there's ^H nowhere.
I open emacs in konsole with -nw option. I can use c-h fine.
I tried it in tty2. ranger is fine in there. c-h works in tty2
I type echo $TERM in konsole and tty2.
In konsole, it's xterm-256color. In tty2, it's just linux.
It relieved me that there's no problem in KDE.

Just replace the map <c-h> with <bs> in ~/.config/ranger/rc.conf .
The reason you should ref the issue:
#559

Note that this only works if <c-h> emits ^H for you. For me it emits ^? whether I'm in or out of tmux.
