Bug where bash can't have \n after $() function,
    Solution: use single quote:
        export PS1='\[\e[32m\]\w\[\e[m\]\[\e[0;33m\]$(git_branch)\[\e[m\]'$'\n\[\e[33m\]# \[\e[m\]'
        $'\n' will convert to new line

$ printf ☠ | hexdump
0000000 98e2 00a0
0000003

# the bit is swaped cuz of endian (98e2 00a0 => e298, a000)
$ printf '\xE2\x98\xA0'
☠

☸ = 98e2 00b8 = \xE2\x98\xB8
icon=$(printf "\xE2\x9D\x8B")
export PS1="\e[1;35m${icon}\u\e[m \e[1;32m\w\e[m\e[0;33m$(__git_ps1 '(%s)')\e[m\n\$ "
