B4J Question unicode problem with jshell

[behnam_tr]

I receive a string from C# with jshell, which contains Arabic and Farsi characters, but instead of the original text, only the symbol ??? I receive.
Should I make changes on the c# side or b4j side??

private void Form1_Load(object sender, EventArgs e)
 {
     Console.WriteLine("این یک متن تستی میباشد"); //not ok
     Console.WriteLine("this is a test text."); //is ok
     Application.Exit();
 }

[CODE lang="b4x" title="b4j code"]
Dim sh1 As Shell
sh1.Initialize("sh1",File.Combine(File.DirApp,ExeFileName),Null)
sh1.WorkingDirectory = File.DirApp
sh1.Run(-1)
Wait For (sh1) sh1_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
If Success And ExitCode = 0 Then
Log("Success")
Log(StdOut) 'print ????????
End If
[/CODE]

You could try adding

Console.OutputEncoding = Encoding.UTF8;

to the c# program.

Thanks, I have already tested this
It works in the console application
But it does not work in the Windows Form application and gives an error

 private void Form1_Load(object sender, EventArgs e)
 {
     Console.OutputEncoding = Encoding.UTF8; //error
      Console.WriteLine("test text....");
 }

[CODE lang="b4x" title="vs2022"]Exception thrown: 'System.IO.IOException' in mscorlib.dll
An unhandled exception of type 'System.IO.IOException' occurred in mscorlib.dll
The handle is invalid.[/CODE]


At the moment, I have to convert it to a console application. Although there was no need for Windows App in this case
Thankful
