A note if you are using tmux with a custom term-info (like many tutorials in the internet instructs you to have something like - italic in vim)
This is what you want inside your tmux.conf (assuming using iterm2 + tmux)

set -g default-terminal 'tmux-256color' # replace this with your custom term-info name
set -ga terminal-overrides ',*:Tc' # this is for 256 color
set -ga terminal-overrides '*:Ss=\E[%p1%d q:Se=\E[ q' # this is for the cursor shape
