    }
    catch (IOException e)
    {
      e.printStackTrace();
    }

    catch (BiffException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    catch (WriteException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

First write some non-ascii data in one of the column and then read the same.. you'll get the answer.
