bootstrap glyphicon unlock is not displaying
<p>I've table with a column status and possible values for status are 1 and 0. </p>

<p>Now I'm trying to show glyph-icon unlock but it is not at all displaying however glyph-icon lock is working fine.</p>

<p>I'm using bootstrap 3.3.5. I don't know why it is not displaying.</p>

<p>when I inspected using google chrome the corresponding icon class is not existed. </p>

<p>So it would be great if someone could provide the content value for unlock</p>

<p>Any help would be greatly appreciated.</p>
