Can your just try:

var multitextfield = g_form.getValue("your_field_name");

alert(multitextfield.length); 

It should give you the size and you can adjust your logic accordingly

this is my script
others must enter more than 256 characters, if there are less, the error msg will be displayed in the service portal. 
it works in the catalog item, the problem is on the service portal.
