Backspace inserts “^?” in vim

Question

I'm using vim editor in linux and every time I type backspace it inserts a "^?" instead. I DID edit the .vimrc file to include backspace=indent,eol,star but it did not help. I also tried backspace=2 and it doesn't work either. The strangest thing is that if I type :fixdel it stops inserting the weird ^? but instead deletes the next character instead of the previous.

Answer 1

In :h fixdel it mentions this:

If the backspace key terminal code is wrong you can use this: >
            :if &term == "termname"
            :  set t_kb=^V<BS>
            :  fixdel
            :endif
Where "^V" is CTRL-V and "<BS>" is the backspace key
        (don't type four characters!).  Replace "termname"
        with your terminal name.

Have you tried that in your vimrc?
