Incorrect handling of non ascii chars

[sbsrouteur]

We encounter an issue with R.Net. I think it is linked to the change of handling of unicode chars in recent R version.

The symptom is as follows :

• Sourcing a file that has accented chars in it will not work from the app using R.Net. However the file works when sourced fom RStudio
• Console string printed by the default console are garbled.
  For example if I send print("é") to evaluate to R.Net the console output will be :

print("é")
[1] "ÿþéÿþ"

I have implement a console device implementing a textencoding work around as follows :

    Public Sub WriteConsole(output As String, length As Integer, outputType As ConsoleOutputType) Implements ICharacterDevice.WriteConsole
        Dim E As Encoding = Encoding.GetEncoding(NativeMethods.GetACP)
        Dim UTF8Bytes() As Byte
        Dim S2 As String = output
        Dim Stx = output.IndexOf(ChrW(2))
        Dim Etx = output.IndexOf(ChrW(3))

        Try
            If Stx > 0 And Etx > Stx + 2 Then
                S2 = output.Substring(Stx + 3, Etx - Stx - 3)
                UTF8Bytes = E.GetBytes(S2)
                S2 = Encoding.UTF8.GetString(UTF8Bytes)
            Else
                S2 = output
            End If
        Catch ex As Exception
            'FIX ME add some tracing??
        End Try

        Console.Write(S2)
        Return
    End Sub

This works for fixing the internal output, but I have the feeling that I am doing things wrong here.

Is there a setting in R.Net that needs to be set to have a proper handling of non ascii chars on non us systems with recent version of R runtime?
