gtk:text-iter-char (iter)

iter -- a gtk:text-iter instance

If the element at this iterator is a non-character element, such as an image embedded in the text buffer, the Unicode #OBJECT_REPLACEMENT_CHARACTER character with the 0xFFFC char code is returned. If invoked on the end iterator, #\Nul with the 0 char code is returned.
