Interactively, make a rectangle selection just before the first column
and then:

C-u C-x r N 65 RET %c  RET

In Lisp, you could write something like

(defun rectangle-char-lines (beg end letter)
   (interactive "r\ncStart letter:")
   (rectangle-number-lines beg end letter "%c "))

and bind it to a key.
