title: Using Alt Codes for drop down in Navigation
body: <p>I have this navigation and I am using Alt Codes "▼" (Alt+31) to show the drop down with the following CSS.</p>
  
  <pre><code>ul&gt;li.drop_down&gt;a:before
  {
  content: "▼"
  }
  </code></pre>
  
  <p>Are there any pontential issues here or am I just better off using a background-image for this purpose. By pontential issues I mean, but not limited to, the character not showing up in different OS or UA and such.</p>
  
  <p>I am using UTF-8 without BOM, New Doc Format = Unix and EOL = Unix Format (don't know if this info will be needed or not).</p>
