winsch, addch and european characters

[Jean Ribiere]

I have problems with waddch and winsch with characters > x'07f'
as european character e acute for instance.

With ncurses-5.5 (linux, slackware-11.0, KDE)
if the character is defined by ch='é',
- wadcch adds the character but it appears in reverse video
  and blinking
- winsch does nothing
if the character is defined by a wgetch :
- waddch is ok
- winsch does nothing

With ncurses-5.4 (linux, slackware-10.2, KDE)
if the character is defined by ch='é',
- wadcch adds the character but it appears in reverse video
  and blinking
- winsch adds the character but it appears in reverse video
  and blinking
if the character is defined by a wgetch :
- waddch is ok
- winsch is ok

I have reinstalled ncurses-5.5 with patch-5.5-20060909 with
the same result.

Is there a solution to this problem ?

I join a small test program.
