Fonts missing in oh-my-zsh on WSL

Im trying to setup Oh-my-zsh on WSL Ubuntu 18.04 with agnoster theme

I already follow this guide : https://blog.joaograssi.com/windows-subsystem-for-linux-with-oh-my-zsh-conemu/

I've installed all the powerline fonts possible, but there are still missing characters :

echo "\ue0b0 \u00b1 \ue0a0 \u27a6 \u2718 \u26a1 \u2699" ±    
