    # process your chosen indicator code(s) with $'..' syntax
    # To get a status indicator shape:
        # 1. Copy the shape to your clipboard
        # 2. Run the command 'echo -n "<symbol(s)>" | hexdump'
        #     This will return something like:
        #         0000000 e2 9c 88                                       
        #         0000003
        # 3. Copy the " e2 9c 88" and replace the spaces with \x => \xe2\x9c\x88
        # 4. Save the new character string in a variable like:
        #     local SYMBOL=$'\xe2\x9c\x88'
        # == Now your symbol can be used in your PS1/PS2 string like "${SYMBOL}" ==
    local AP=$'\xe2\x9c\x88' # Airplane
    local RA=$'\xe2\x98\xa2' # Radioactive
    local PF=$'\x28\xe0\xb8\x87\x27\xcc\x80\x2d\x27\xcc\x81\x29\xe0\xb8\x87' # Pissed off face
