Ncurses is unwilling to bend to nano.  See: https://lists.gnu.org/archive/html/bug-ncurses/2016-01/msg00006.html.

A small reason not to show these placeholder "block characters" is that the relevant code points have not been assigned.  But still, it's much better to show something than deceptive blank space.

Open the attached file in nano, and see how the first line (after the A:) appears to be empty.  But when you open it in vim or emacs or dex or joe, there are four "block characters" there, showing the codes 0A1000, 0B2000, 0C3000 and 0D4000.

I think nano should show these blocks too, just like on the D: line.  There is no reason why the codes on the A: line should be treated different; they are valid code points.

(The B: and C: line contain some invalid Unicode code points, to compare how different editors handle these.  The representation by vim is the nicest.  Line E: contains two accented characters, plus two with a combining accent.  No problems there.)
