the prompt is not working

according to the screen you've provided, the prompt works but your terminal is unable to display some symbols. It's fine, all you need is to change the font in your terminal app. If none of your favorite fonts works then you can try to install Powerline fonts and use one of them

thanks for you help! i installed the fonts-powerline package and tried it with "Droid Sans", no it is working :) 👍
