How can I use these red and green arrow signs in the bash prompt?

[33[01;34m]→ w[33[00m]$ '
else
PS1='${debian_chroot:+($debian_chroot)}→ w$ '

You can use bash’s PROMPT_COMMAND to run a function which builds your prompt, e.g.:
PROMPT_COMMAND=build_prompt
build_prompt() {
EXIT=$? # save exit code of last command
red='[e[0;31m]' # colors
green='[e[0;32m]'
cyan='[e[1;36m]'
reset='[e[0m]'
PS1='${debian_chroot:+($debian_chroot)}' # begin prompt
if [ $EXIT != 0 ]; then # add arrow color dependent on exit code
PS1+="$red"
else
PS1+="$green"
fi
PS1+="→$reset $cyanw$reset $ " # construct rest of prompt
}
Add this code to your ~/.bashrc file and open a new terminal or run . ~/.bashrc in an existing one for the changes to take effect. Note that I added the usual $ at the end, this prints $ normally and # if you’re root, thus preventing you from running commands as root unwittingly. The false command is a good way to test the non-zero exit code variant:

Hey man. This idea is crazy fascinating. I came up with the exotic idea awhile back to use ϟ for my prompt instead of $ only when in a Unicode environment, which I'm frequently not.
