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,

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

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...
