Powerline can use a patched font (and is configured to do so) to display some fancy symbols. To take advantage of this, you will need to patch your font of choice. Alternatively you may download any of these pre-patched font.
Or you could configure g:Powerline_symbols to not be fancy if you do not care.
:Open will open a directory relative to ~/Code. Change g:project_dir if you use a different path.
