I'm running emacs on macOS, and I've run into problems with ansi-term. Using bash itself works fine, but as soon as I run a simple application with a command line interface, my <delete> and arrow keys break.

Instead of the usual delete behaviour, emacs prints ^h, and instead of moving in the direction indicated by the arrow keys, emacs prints ^[OA, ^[OB, ^[OC, and ^[OD. How can I fix this?

I've found a solution. C-c C-j switches the terminal from term-char-mode to term-line-mode, and fixes the behaviour inside the application. Once I'm finished with the application, C-c C-k switches the terminal back to term-char-mode.
