ZSH (O-M-Z + powerlevel9k) + glyphs + console only (Ubuntu server edition): How to get all 3 working?

So I have installed ZSH + oh-my-zsh + powerlevel9k on my Ubuntu server edition. While it's working including the colors (I used darkorange background to display current user), I cannot get the glyphs to work. In place of the home folder icon () when I'm on the user home folder, all I see is a triangle. Can someone please advice how this can be done? Thanks
