title: Bootstrap List Filter problems with Turkish "İ" character
body: <p>I use bootstrap list filter ( <a href="https://github.com/stefanocudini/bootstrap-list-filter" rel="nofollow">see github</a> ) but I have a problem with Turkish "İ" character, when I type lowercase "i" i got no results.</p>
  
  <p>You can see my code snippet:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$(window).load(function(){
  $('#mylist').btsListFilter('#filterinput', {
      itemChild: 'span'
  });
  });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/&gt;
  &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="http://labs.easyblog.it/bootstrap-list-filter/bootstrap-list-filter.src.js"&gt;&lt;/script&gt;
  
  &lt;form role="form"&gt;
    &lt;div class="form-group"&gt;
     &lt;input class="form-control" id="filterinput" type="search" placeholder="type istanbul..." /&gt;
    &lt;/div&gt;
    &lt;div id="mylist" class="list-group"&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;İstanbul&lt;/span&gt;&lt;/a&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;İzmir&lt;/span&gt;&lt;/a&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;Ankara&lt;/span&gt;&lt;/a&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;Hatay&lt;/span&gt;&lt;/a&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;Teksas&lt;/span&gt;&lt;/a&gt;
     &lt;a class="list-group-item" href=""&gt;&lt;span&gt;Newyork&lt;/span&gt;&lt;/a&gt;
     &lt;!-- FILLED DYNAMICALLY --&gt;
    &lt;/div&gt;
   &lt;/form&gt;</code></pre>
  </div>
  </div>

  <p>Type <strong>istanbul</strong> with lowercase.</p>
