In this method:

        ' FileToStr() VFP equivalent
        ' expC1 File name
        Public Function FileToStr(ByVal tcFileName As String) As String
            Dim loFile As IO.StreamReader
            Dim lcString As String
            Try
                loFile = New IO.StreamReader(tcFileName, System.Text.Encoding.Default)
                lcString = loFile.ReadToEnd()
                loFile.Close()
            Catch loError As Exception
                oApp.ErrorSetup(loError)
                lcString = ""
            End Try
            Return lcString
        End Function

If the file being read contains some French characters, they are being shown really weird on the page. What adjustment would be needed to assure a proper encoding?
