how to export pdf to a Unicode text file with Crystal reports in asp.net

Hi,

I wanted some help on crystal reports...I have not worked on it before.....

I have a requirement in a .net application where I need to download PDF's  in different languages.

I am trying to implement the same using crystal reports. I am using the components of crystal decisions that comes along with dotnet installations.

Does anybody knows whether crystal reports support all the languages in the world(unicode support)?

i am export data into pdf using this code for your info:

Protected Sub Button2_Click(sender As Object, e As System.EventArgs) Handles Button2.Click
        Export_Report(1)
    End Sub

Private Sub Export_Report(ByVal oexptype As Integer)
        Try
            Dim DT As New System.Data.DataTable
            Dim conn As New SqlConnection("Data Source=PRASAD-PC\SQLEXPRESS;initial catalog=Practice_Db;persist Security info =true;user id=sa;password=sa123")
            Dim da As New SqlDataAdapter("select * from Userdaycounts", conn)
            da.Fill(DT)
            If DT.Rows.Count > 0 Then
                Dim reportDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument
                reportDocument.Load(Server.MapPath("~/Userwisecounts.rpt"))
             
                Dim rptby As String = ""
                Dim GrandTotal As String = ""


                Try

                    rptby = "Jan 30th  ,  2013 - User wise counts"
                    GrandTotal = "Grand Total"

                Catch ex As Exception

                End Try
                reportDocument.SetDataSource(DT)
                reportDocument.SetParameterValue("rptby", rptby)
                reportDocument.SetParameterValue("GrandTotal", GrandTotal)
                Dim oselectedtype As ExportFormatType
                If oexptype = 1 Then
                    oselectedtype = ExportFormatType.Excel
                ElseIf oexptype = 2 Then
                    oselectedtype = ExportFormatType.PortableDocFormat
                End If
               reportDocument.ExportToHttpResponse(oselectedtype, Response, True, "MTReportbyMessages")
            Else
            End If
        Catch ex As Exception
            Label1.Text = ex.Message
        End Try
    End Sub
