      I think I understand what's going on... If I'm correct, you are unable
      to hide the special characters because your terminal's default
      background color is black, but its "color palette" doesn't contain
      black. Note that in addition to the default "Text color" and "Background
      color", color terminals have what is known as a "Color palette". The
      colors in the color palette (also known as the color cube) are
      completely independent of the Text color and Background color. Vim's
      ctermfg/ctermbg mechanism works properly only for colors in the color
      palette: thus, setting ctermbg or ctermfg to the default Background
      color won't work unless the default Background color happens to be in
      the color palette. In other words, the workarounds will work only if the
      default background color is in the color palette.

      I don't know what color terminal you're using, but I was able to
      reproduce what you were seeing in gnome-terminal. I was able to fix it
      by changing to a color palette that contained black...

      On the gnome-terminal title bar...

      Edit->Profile Preferences...

      ...brings up a dialog with multiple tabs. On the "Colors" tab, you can
      define the default foreground and background colors with the "Text
      color" and "Background color" color pickers. Under "Palette", there's a
      combo box that allows you to select from a number of built-in schemes. I
      was originally using "Tango", which had a couple different shades of
      grey, but no black. The others (Linux console, XTerm and Rxvt) all had
      black as the first color in the palette. After I had switched to "Linux
      console", the workarounds were successful...
