I made the following function

(defun indicator-attributes ()

     (setq display-fill-column-indicator-character ?\u2503)

     (set-face-attribute 'fill-column-indicator nil :background "green" :height 1.0))

I have another function to enable global-display-fill-column-indicator-mode

(defun  colum-indicator () 
     (interactive) (global-display-fill-column-indicator-mode))

If I call (indicator-attributes) in my init file, then do "M-x colum-indicator" in a buffer, I get the old character.

But if I change colum-indicator to include (indicator-attributes) after setting the global mode, I get
the correct wider character if I do "M-x colum-indicator" in a buffer.

(defun  colum-indicator ()
 
     (interactive) (global-display-fill-column-indicator-mode) (indicator-attributes))
