If you are here maybe you are looking for simple solution. Here is my solution. It is not perfect, but it is very simple

var max_length = 3;
    tinymce.init({
        selector: '#description',
        // some my settings for tiny mce
        toolbar: ' undo redo | bold italic | formatselect',
        setup : function(ed) {
           // important part
           ed.on("keypress", function(event){
                // get content of the tinymce and remove tags
                // tinymce will be adding tags while you type in it.
                // when tags are removed, you will heave real input length (the one that customer sees)
                var content =  tinymce.activeEditor.getContent().replace(/(<([^>]+)>)/ig,"");
                // now just compare that length to your prefered length.
                // if it is larger or same, return false, and that will disregard last input.
                if(content.length >= max_length){
                    return false;
                }
            });
        }

    });
