Counting number of characters typed on textarea using jQuery

There is textarea for input with id mytext
<textarea id="mytext" ></textarea>
A  div with id char_counter for counting number of characters typed in textarea
<div id="char_counter"></div>

jQuery code: using keyup to update the characters typed.

    $('#mytext').keyup( function(){
   var text_length = $('#mytext').val().length;

    $('#char_counter').html(text_length + ' characters  are typed');


if space is not counted, we should use 
var text_length = $.trim($('#mytext').val()).length;
