One way to do it (which works for both repeating a character or a
string):

--8<---------------cut here---------------start------------->8---
(defun foo/repeat-string (n str)
  (with-temp-buffer
    (dotimes (_ n)
      (insert str))
    (buffer-string)))
--8<---------------cut here---------------end--------------->8---

Bye,

Pretty, but there is an easier way and you know it :)

  (make-string 3 ?w) ; www

But what don't you do to get char/string transparency...

;; Set MY-VAR to a string of 314 x's.
(setq my-var  (make-string 314 ?x))
