title: Wrong bullet train oh-my-zsh theme render
body: <p>I have like an encoding error when the prompt is rendered.</p>
  
  <p>I just installed the bullet-train theme for the oh-my-zsh plugin.</p>
  
  <p>I installed the Powerline fonts as it is indicated in the bullet-train.zsh-theme file but though, my terminal doesn't seems to care.</p>
  
  <p>It seems to be the right colors but there is "?" characters instead of the normal rendering.</p>
  
  <p>Whereas it should be rendered like this: <a href="https://github.com/caiogondim/bullet-train-oh-my-zsh-theme" rel="nofollow">https://github.com/caiogondim/bullet-train-oh-my-zsh-theme</a></p>
  
  <p>I have a MacBook Pro and I use iTerm2.</p>
