of course 2.8.5dev.16 is rather old (more than a year).  But the underlying
version of ncurses is more important.  If it's not the wide-character
configuration of ncurses, your results won't be as good.

(this comment isn't clear - are you talking about setting display character
set to something?)

It seems to work for me.  I generally use the uxterm script (which has
the same general effect).  Fonts can be a problem.  Checking, I see
the characters using

*VT100*font5:   -misc-fixed-medium-r-normal--18-120-100-100-c-90-iso10646-1
*VT100*font6:   -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1

While the latter is more readable, I've found that it isn't as complete.
But for this example, either works (for me - using ncursesw).

Perhaps one of these:

        a) using slang or ncurses rather than ncursesw
        b) using an older version (?) of the fonts
        c) using an older version of ncursesw (5.4 is recommended - best
           results with the rollup patch from April).
