Hi-
With using libncursesw from ncurses-5.7-20090808 on i686-pc-linux-gnu, I
tried to unget_wch characters then retrieve them using getn_wstr. While
that seems to work for ASCII characters, it doesn't work for non-Latin-1
characters, apparently.
I've attached a sample program where I've tried to do that. I unget a
newline and U+017C and try to retrieve it with getn_wstr. getn_wstr
returns OK, and the resulting string from getn_wstr is a null string.
Thanks,
Mike Gran
