problem in reading the columns from an xls file

I am having a problem in reading the columns from an xls file.

Following is the code:
workbook = Spreadsheet::ParseExcel.parse(params[:dump][:file])
        worksheet = workbook.worksheet(0)

        skip=0
        worksheet.each(skip) { |row|

        puts row.at(0)

        }

I am storing "Customer" in the first row first column. When I print, it
is received as C[]u[]s[]t[]o[]m[]e[]r[] (I mean a box in between each
letter).
Am i missing out anything in the code?

Please help.

Thanks in advance.

row.at(0).to_s('latin1') has fixed the issue.
