The problem: some chars in cs_CZ.UTF-8 locale (and probably other locales as well) are single bytes, but not ASCII, thus they are not correctly processed. The attached patch should fix it. But it is possible that there are more such "broken" calls in ncurses.
I can reproduce this with 20101128 patch too.
It's fixed in upstream patch 20101211. Thanks.
