Fonts issue. Install a ttf one of the prepatched powerline fonts. Conhost doesn't handle fallback or OTF yet.

You may also have to configure your command prompt to use the font you want. You can modify the properties in an active command prompt by right-clicking the title bar (or opening a desktop/start menu shortcut's properties)

If you want to use a font that isn't displayed in the list, you can try adding entries to the registry for the fonts you wish to use (the string names should be unique numbers and the values should be font names):

Yes, but they must be ttf monospaced.

Thank you for help me figure out what was the problem. It's working now! 😄

My problem was that I installed the fonts by console, executing the install.sh (source: https://github.com/powerline/fonts), so I tried again but adding the fonts to Windows by Control Panel > Appearance and Personalization > Fonts and configuring my console with the next properties:

Again, thank you! 👍

Thanks for the smily face =]

I couldn't find one for consolas

I know @AlonsoCN has answered this question very well. But there is still one step missing, so I would llike to share again in 2019.

# clone
git clone https://github.com/powerline/fonts.git --depth=1
# install
cd fonts
./install.sh
# clean-up a bit
cd ..
rm -rf fonts

Downloading font from https://dejavu-fonts.github.io/, double click you will see an install button.

You can modify the properties in an active command prompt by right-clicking the title bar (or opening a desktop/start menu shortcut's properties)

Adding on to what @duocang said you might need to get DejaVu Sans Mono for Powerline to see the branch icons for git.

Solution (tried successfuly in Ubuntu 22.04):

sudo apt install fonts-font-awesome fonts-lato
