I need to see the space characters but I can't set it for the life of me.

I went to customize the Whitespace Display Mapping and this is what I found. Notice that the mapping for the space is set to be ".". It doens't work of course:

INS DEL Character Mapping:
            Char Kind: Value Menu Space
            Char:  
            Vector List:
            INS DEL :
                        Vector Characters:
                        INS DEL Char: .
                        INS
            INS
...

I even included this into .emacs

(setq whitespace-display-mappings '((space-mark 32 [46])
       (newline-mark 10 [36 10]) (tab-mark 9 [187
      9] [92 9])))

Still nothing.

Maybe someone know what is the problem here? I just want the whitespace overlay to show the " " character as a ".".

Thanks for your time and help in advance.

    The default behavior of `whitespace-mode` is to show a space as a centered dot character. Have you tried using `whitespace-mode` without making any modifications? Try opening any file in `fundamental-mode` and type `M-x whitespace-mode` without any whitespace configuration settings. – lawlist Jul 15 '15 at 22:17
  • For the record, the visual display of the space-mark it is not an overlay -- it is a glyph that is displayed via the `buffer-display-table`. – lawlist Jul 15 '15 at 22:25

    Jenia Ivanov: Does your `whitespace-style` variable contain `space-mark` ? (or if using the customize interface: `(Mark) SPACEs and HARD SPACEs` ?) – phils Jul 16 '15 at 01:15

Your settings work. Make sure that you don't have grayish window background.

As phils already said in the comments whitespace-style needs to include space-mark.

See my answer here for details.
