streamwriter problems

I am using io.streamwriter.write to output database fields to a text file. I am getting some strange characters appearing in the text file, for example where there is an apostrophe in a line of text the output file shows a series of garbage characters (see below)

Original text:
organisation's

text from output file:
organisationââ¬â¢s

it looks like it's converting the apostrophe to ââ¬â¢

This is also happening with other special characters.

here is my code:

 'itterate through tbl_upload and write out csv test file
        Dim file As String = "c:\local_audits\out.txt"
        Dim sw As New IO.StreamWriter(file)

        'Loop through each row/field and output it to a text file
        '    separating each field by $ and delimiting rows with ^

        Form4.Label2.Text = "Creating Temporary File"
        Form4.Refresh()
        Dim uploadrows As Integer
        uploadrows = tbl_upload.Rows.Count - 1
        Dim aa As Integer

        For aa = 0 To uploadrows
            For a = 0 To 116
                If a < 116 Then
                    If IsDBNull(tbl_upload.Rows(aa).Item(a)) Then
                        sw.Write("\N$")
                    Else
                        sw.Write(CStr(tbl_upload.Rows(aa).Item(a)) + "$")
                    End If
                Else
                    If IsDBNull(tbl_upload.Rows(aa).Item(a)) Then
                        sw.Write("\N")
                    Else
                        sw.Write(CStr(tbl_upload.Rows(aa).Item(a)))

                    End If

                End If
            Next
            sw.Write("^")
        Next
        'cleanup
        sw.Close()
        sw.Dispose()

does anyone have any ideas as to why? and how it can be cured.Start Free Trial
