This was covered on the list recently. For the whole thread, search
cftextarea: how to count characters

Reprise relevant js:

   var oEditor = FCKeditorAPI.GetInstance('theBody');
   var theBodyTest = oEditor.GetXHTML(true);
   if (theBodyTest.length==0) {
     alert('You need to enter something for the body of your story.');
     return false;
   }


Cheers,
Kris
