utf8

[Ricardo Cantu]

It seems that the handling of utf8 chars may have changed between versions 5.4 
and 5.5.

The following code would display all the box drawing elements fine in 5.4 but 
not in 5.5.

I'm patched to ncurses-5.5-20051231.patch

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <ncurses.h>
