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.

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?

1There's a deeper issue of
TERMbeing wrong, and / ortermcap/terminfohaving a different idea ofkb/kbsthan what the keyboard actually produces. An ever-green problem in some Linux-shaped corners of the land. :) – Sato Katsura Aug 30 '16 at 20:55
