[fetter-devel] More on overloaded C++ functions -> Lisp ???

OK, here is a second case of the above, a little hairier:

(cl:defun FTFont-Render (this string)
  (vzn:virtual-funcall this 6 0 :pointer this :pointer string :void))
 (cl:defun FTFont-Render-1 (this string)
  (vzn:virtual-funcall this 7 0 :pointer this :pointer string :void))
 
This is still the char vs wchar thing, but now I cannot tell which is 
which.
