Often I want to put the string "<!-- -*- coding: utf-8; -*- -->\n" at
the top of the current buffer. However, I don't want to lose my place
(the point) or any defined region. Optimally, such a function would
know the mode of the current buffer and enclose the string in the
mode-appropriate comment characters. Is there such a function? If not
how would one code it?
Thanks for your solutions.

The following seems to work.
(defun my-header ()
"put a commented header at the beginning of the buffer"
(interactive)
(save-excursion
(beginning-of-buffer)
(let ((start (point)))
(insert "-*- coding: utf-8; -*-")
(comment-region start (point))
(newline))))
