Seems that face attributes can be set for fill-column-indicator before calling
display-fill-column-indicator-mode. But not for display-fill-column-indicator-character.
It would help if the customisation behaviour is made consistent such that one can
customise the fill-column-indicator properties before enabling the mode. With
the customisation remaining effective when the mode is disabled.

Please show how you tried doing that, starting from "emacs -Q". There
are many possible ways of customizing face attributes, and we need to
know which one you found not functioning in this case.

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))

It's the same issue as with fill-column:
display-fill-column-indicator-character is a variable that
automatically becomes buffer-local when set (see its doc string). So
your setq is in effect only for a single buffer: the one in which
Emacs loads and evaluates the init file.
You should use setq-default instead.
This is not a bug.

Thusly I have the same problem because for setq-default, the new value is seen in buffers that do not have their own values for the variable.
But I want to change the value even if buffer has its own value.
