The function help-setup-xref is already used in describe-char as
(help-setup-xref nil (interactive-p))
It is called before the old contents of the help buffer is replaced with
the output of `describe-char'. This is necessary to record the previous
position of point. But since at this moment the help buffer doesn't contain
the new output of `describe-char', we should use nil for the first
argument `item' of the function `help-setup-xref' here, and should set
`help-xref-stack-item' explicitly later when the help buffer is ready.

Unless you propose a better solution, I will add a comment.
