          selector: "textarea",
          plugins: [
              "advlist autolink lists link image charmap print preview anchor",
              "searchreplace visualblocks code fullscreen",

      });
    </script>

how to limit characters to 500?

I don't know how to do that in tinymce 4.0 but you should do that counting on the server side. — yotamN, Sep 27 '14 at 16:28
Do you mean like this : http://www.tinymce.com/wiki.php/TinyMCE3x:How_to_limit_number_of_characters/words ? — laruiss, Sep 27 '14 at 16:37
Have you tried to add `maxlength` attribute: ``? Be carefull, there is [an open issue](https://github.com/angular-ui/ui-tinymce/issues/145) related to AngularJS binding. — naXa stands with Ukraine, Dec 08 '15 at 13:53

I added the "stopPropagation" line, in order to prevent the user from continuing to enter characters: 1 - in the html code of the textarea it is necessary to include the value of maxlength and Id.
2 - in script part, code below. If you want, uncomment the alert() line, and put your message.

<script type="text/javascript">
  tinymce.init ({
    ...
    ...
      setup: function(ed) {
        var maxlength = parseInt($("#" + (ed.id)).attr("maxlength"));
        var count = 0;
        ed.on("keydown", function(e) {
          count++;
          if (count > maxlength) {
            // alert("You have reached the character limit");
            e.stopPropagation();
            return false;
          }
        });
     },

<textarea type="text" id="test" name="test" maxlength="10"></textarea>

It can work, but I don't know how to let it can press delete key...

  setup: function(ed) {
        var maxlength = parseInt($("#" + (ed.id)).attr("maxlength"));
        var count = 0;
        ed.on("keydown", function(e) {
            count++;
            if (count >= maxlength) {
                alert("false");
                return false;
            }
        });
    },
