I agree that it would be nice, but other implementations appear to agree.
You'll have to use touchline or touchwin to get the effect you want.

Cool. touchline worked. However, is there any way I can update/redraw only a
limited number of columns, instead of the whole line? If you are wondering
what I am trying to do, I am trying to have a shadow effect for buttons :-)

I think you could do that by making a subwindow (or derived window: subwin/derwin) and touching _that_ window. That's a little complicated, but the only thing that comes to mind.

Also, is there anyway I can print non-ASCII characters (eg. UTF-8)? Simply
using printw familty of functions prints multiple characters in place of one
UTF-8 character.

For that, you need your locale setup, build with ncursesw and to call
        setlocale(LC_ALL, "");
in the application before initscr/newterm.
