When performing a .trim() function on a string pulled via the .text() tag in jQuery, will convert into a special space that will not be removed.
Example:
<div id="div1"> This is text </div>
<script type="text/javascript">
jQuery(document).ready(function() {
trimString = jQuery.trim($('#div1').text());
</script>
I was able to catch the Unicode character, which ended up being 160, by using:
alert(trimString.charCodeAt(0));
After performing a regex replace on the string, I was able to achieve a truly trimmed string.
<script type="text/javascript">
$(document).ready(function() {
trimString = $('#div1').text();
var re = new RegExp(String.fromCharCode(160), "g");
trimString = jQuery.trim(trimString.replace(re, " "));
});
</script>

How is the code that you have published any different from the native String.trim()? There is no sense in adding library overhead for a native function.
String.trim() will only remove whitespace. While $.trim(string) will remove newlines, spaces, and tabs. It’s also supposed to remove non-breaking spaces, but it appears it relies upon the functionality of the browser’s javascript capabilities. At least it did at time of writing.
