Printing with ReportViewer Asp.Net

Good afternoon, I'd like some help.

I am generating an impression by ReportViewer with Visual Studio 2010, the report is generated correctly but in the print preview the Print button in the report does not appear. So I decided to convert the print to PDF so yes, the option to print appears, but where it has an accent, it looks like this:

      teste de então         - que o certo seria - teste de então

This column has already tried to put it as Varchar or Nvarchar and has the same problem.

Follow the code of the report page:

ReportViewer1.Reset();
                    ReportViewer1.LocalReport.DataSources.Clear();

                    // atribuiu o caminho onde está o relatorio .rdlc
                    ReportViewer1.LocalReport.ReportPath = @"Relatorio\RelAcompanharOcorrencias.rdlc";

                    // cria e atribui o datasource
                    ReportDataSource dts = new ReportDataSource("DataSet1", dt);
                    ReportViewer1.LocalReport.DataSources.Add(dts);
                    //ReportViewer1.LocalReport.Refresh();

                    var bytes = ReportViewer1.LocalReport.Render("PDF");
                    Response.Buffer = true;
                    Response.ContentType = "application/pdf";
                    Response.AddHeader("content-disposition", "inline;attachment; filename=Sample.pdf");
                    Response.BinaryWrite(bytes);
                    Response.Flush(); // send it to the client to download
                    Response.Clear();

Below is the code for the button that fires print:

DataTable dt = new DataTable();
            if (gridHome.Rows.Count > 0)
            {
                dt = ObjOcorrencia.converterGridViewParaDataTable(gridHome);
                Session["dtimpressao"] = dt;
                Redirect("Relatorio/fRelAcompanharOcorrencias.aspx","_blank","");
            }

If someone has a solution either to put the button print or to correct this accent problem thank you

Thank you in advance.
