You can put this in your .emacs:

(defun go-to-char (arg char)
  "Go to ARG'th occurrence of CHAR.
Case is ignored if `case-fold-search' is non-nil in the current buffer.
Goes backward if ARG is negative; error if CHAR not found."
  (interactive "p\ncGo to char: ")
  (search-forward (char-to-string char) nil nil arg))

(define-key global-map (kbd "C-c g") 'go-to-char)

This is derived for zap-to-char.

Put this in you .emacs:

(defun go-to-non-alphanum (arg)
  "Search forward for a whitespace."
  (interactive "p")
  (re-search-forward "[^A-Za-z1-9]" nil nil arg))

(define-key global-map (kbd "C-c n") 'go-to-char)

GoodBye
