Wide characters and menu

I have a database (PostgreSQL) with tables stored in Unicode (Cyrillic).
Seems my code doesn't work when I try to use output of the database query as menu items. Here's a code:

#include <ncursesw/panel.h>
#include <ncursesw/menu.h>
#include <wchar.h>
PGconn *connect;
connect = PQconnectdb(ConnectionString);
PGresult *OrderData;
OrderData = PQexec(connect, Query);
my_items = (ITEM **)calloc(PQntuples(OrderData)+1, sizeof(ITEM *));
for(i = 0; i < PQntuples(OrderData); ++i) {
  my_items[i] = new_item(PQgetvalue(OrderData, i, 1), "");
my_menu = new_menu((ITEM **)my_items);
Compile: gcc 1.c -lmenu -lncursesw -lpq
So, with parameter PQgetvalue(OrderData, i, 0) my function works fine because this column is 'id'. But result of PQgetvalue(OrderData, i, 1) contains cyrillic symbols and my code doesn't work.
