Android Question Save CSV file in UTF8

[Mostez]

I use this code to export B4Xtable contents to CSV file, then I use FileProvider to open it by Excel or Google Sheets, they do open the file OK, but unfortunately both of them dont show Arabic letters correctly.
I have to open saved CSV by notepad then save it in UTF8 and reopen it again by Excel or Google Sheets, is there any method to save the CSV file in UTF8?

thanks

Dim st As clsSysTools
            st.Initialize
            Wait For (CallSub3(st, "ExportTableToCSV",Table,Filename)) Complete (Exported As Boolean)
            If Exported Then
                ToastMessageShow("Data Exported OK",False)
                Dim in As Intent
                in.Initialize(in.ACTION_VIEW, "")
                Starter.Provider.SetFileUriAsIntentData(in, Filename)
                in.SetType("text/csv")
                StartActivity(in)
                Return True

Public Sub ExportTableToCSV(Table As B4XTable,ExportFileName As String) As ResumableSub
    Try
    Dim data As List
    data.Initialize
    Dim CSVHeaders As List
    CSVHeaders.Initialize
        'Dim rs As ResultSet = Table.sql1.ExecQuery("SELECT * FROM data")
        Dim o() As Object = Table.BuildQuery(False) 'True to include the page LIMIT in the query.
        Dim rs As ResultSet = Table.sql1.ExecQuery2(o(0), o(1))
    Do While rs.NextRow
        Dim row(Table.Columns.Size) As String
        For i = 0 To Table.Columns.Size - 1
            Dim c As B4XTableColumn = Table.Columns.Get(i)
            row(i) = rs.GetString(c.SQLID)
        Next
        data.Add(row)
    Loop
        For i = 0 To Table.Columns.Size - 1
            Dim c As B4XTableColumn = Table.Columns.Get(i)
            CSVHeaders.Add(c.Title)
        Next
    rs.Close
    Dim su As StringUtils
    Dim StorageDir As String = Starter.Provider.SharedFolder
    su.SaveCSV2(StorageDir, ExportFileName, Chr(9), data,CSVHeaders)
        Return True
    Catch
        Log(LastException)
        Return False
    End Try
End Sub

Everything is explained here: https://www.b4x.com/glossary/csv/

Your file is saved in UTF8. The problem is in old versions of Excel which doesn't support UTF8 CSV files.
