oh my zsh showing weird character '?' on terminal

Question

I have installed iTerm2 and Oh-my-zsh. However there is a weird question mark that is coming ever since I have changed ZSH-THEME to "agnoster".

Attaching the screenshot for the same.

I thought powerline would help but that doesn't seem to happen. Can can anyone help me with this?

Run step 1-4 in your iterm2/terminal and you are done.

1. git clone https://github.com/powerline/fonts (clone it anywhere, You can remove cloned dir after step-4)
2. cd fonts
3. ./install.sh
4. Open iTerm2->Preferences->Profiles->Text->Change Font-> Meslo LG S DZ Regular for Powerline
5. Reopen the terminal and you are done.

Edit: If you are not using iTerm you can simply change the default macOS Terminal Preferences. (Thanks to Kewal)
