Find out the unicode character code of icon-font icons
<p>I have a font file called <code>icon-font.woff</code>, and I have the corresponding SVG file. It has some number of icons inside. now i would like to use these icons in my html file using css like this:</p>

<pre><code>.icon-add-contact:before{content:""}
</code></pre>

<p>But I don't know what is the value I need to give in the <code>content</code> above. And I don't know which value goes to which icon.</p>

<p>How to handle this?</p>
