Package: libncursesw5
Version: 5.5-1
Severity: normal
Tags: patch
The wins_nwstr() logic of inserting characters fails on the cyrillic
charcters, because they aren't 'wide' (wcwidth(char) == 1), but they
aren't ASCII chars, so _nc_insert_ch() function (called from the
wins_nwstr() in case of non-'wide' char) fails to put the correct
character in the window.
The bug was discovered by Ivan Loh (loh at 1917 dot com) by trying to
use aspell with russian texts.
Attached patch fixes the problem.
