powerline fonts doesn't work on vim/debian
<p>I have clone the repos of powerfonts and install it. And I config my vim as</p>

<pre><code>let g:airline_powerline_fonts=1
</code></pre>

<p>However it doesn't work on debian, even I clean the font cache and restart server. But it does work on my mac.</p>

<p>I wonder what's wrong with it. Should I config font on debian?</p>
