This seems to work here:
(defun my-font-lock-string (string &optional mode)
(let ((mode (or mode major-mode)))
(with-temp-buffer
(insert string)
(funcall mode)
(funcall font-lock-fontify-buffer-function)
(buffer-string))))
(my-font-lock-string "\"\\\\(1\\\\|2\\\\)\"" #'emacs-lisp-mode)

Hm, maybe not. When I do (message (my-font-lock-string ...)) it prints
the string readably rather than colorized. Hopefully someone else will
know how to get around that.
