What does Emacs mean by "Emacs 23"? See my mail, where "Help > Send bug
report" reported the version and build information.
If you understand the problem, and it is in fact user ignorance, please feel
free to explain.
FYI, the display-table entries were generated using Kim's proposal for a
post-Emacs 22 release `make-glyph-code':
(defun make-glyph-code (char &optional face)
"Return a glyph code representing char CHAR with face FACE."
(if face (logior char (lsh (face-id face) 19)) char))
The face used was this:
(defface my-highlight
'((((type x w32 mac graphic) (class color))
(:box (:line-width 3 :style pressed-button)))
(t (:inverse-video t)))
"..." :group 'faces)
The vector was generated using this:
(aset standard-display-table
?\014
(vconcat "\n"
(mapcar (lambda (c) (make-glyph-code c 'my-highlight))
" Section (Printable Page) ")))
I admit to not understanding a lot about glyphs, character codes, or
Unicode. Perhaps it is silly to expect that `make-glyph-code' would work as
proposed for Emacs 23 also. Please explain. Otherwise, if this is a bug,
HTH.
