well, Erwin Waterlander reported several issues (and I've been working
on those, but have not investigated all).  Here are a few:

        a) the ncurses port works in a regular Windows console window,
           and in ConEmu - but does not initialize in Console2.

           It would be very useful to identify the source of the problem.
           PDCurses works in Console2, though it has its own share of
           problems :-)

        b) there are differences between those three (as well as with
           mintty) for the ability to display double-cell characters.

           My current understanding is that a console application cannot
           tell much about the font in use (aside from its name), and
           so cannot tell whether a given font uses double- or single-cells
           for some problematic line-drawing characters.  (It would be nice
           if I'm wrong, and someone shows how to do this :-)

        c) I started some experimental code to improve screen-painting
           by reducing the amount of output.  It doesn't handle the
           double-width example which Erwin gave me.  (Solving this
           may actually depend on (b) mentioned above).

        d) Input of Unicode (wide) characters is incompletely tested.

           As I did for output, some changes are probably needed.
           MinGW's wide-character support builds, but does not work
           well enough for use.

        e) Erwin also had comments about surrogate pairs, screen flicker.
           I'm unsure if these are addressed.

(as usual, my progress on these depends on time available after doing
normal maintenance...)
