Hm I tried out 

(defun overlay-dired-filetags ()
  (save-excursion
    (goto-char (point-min))
    (while
	(re-search-forward "\\(_ftag_\\)" nil t)
      (let
	  ((ov (make-overlay (match-beginning 1) (match-end 1)))
	   (tag (propertize " ⚜ " 'face 'bold)))
	(overlay-put ov 'overlay-tag t)
	(overlay-put ov 'display tag)))))


(add-hook 'dired-mode-hook 'overlay-dired-filetags)

But 
my-auctex-init_ftag_emacs.el

Still gets displayed as 
my-auctex-init_ftag_emacs.el

What do I miss?
