已从.NET启动进程，但RedirectedStandardOutput不支持UTF-8

我试图使用以下代码从.NET调用php的HTML净化器：

    Process myProcess = new Process();

    myProcess.StartInfo.FileName = "C:\Path\to\php.exe";
    myProcess.StartInfo.Arguments = "C:\Path\to\purify.php";
    myProcess.StartInfo.UseShellExecute = false;
    myProcess.StartInfo.RedirectStandardOutput = true;
    myProcess.StartInfo.RedirectStandardInput = true;

    myProcess.Start();

    StreamWriter myStreamWriter = myProcess.StandardInput;

    String inputText;

    inputText = txtCodes.Text;
    if (inputText.Length > 0)
    {
        myStreamWriter.Write(inputText);
    }
   myStreamWriter.Close();

    labMsg.Text = myProcess.StandardOutput.ReadToEnd();

    myProcess.WaitForExit();

    myProcess.Close();

。。一切都很好，除了。。。我无法取回非asci字符。例如，在输入中提供一些韩语字符会返回问号作为输出

即使HTMLPurifier函数是ByPasd函数，并且我只是简单地提供输入.NET，将其存储在php变量中，然后将该变量回显到输出中，这种情况也会发生

有什么想法吗

试试看

myProcess.StartInfo.StandardOutputEncoding = System.Text.Encoding.UTF8;

试一试

谢谢你的指点。我确实设法解决了这个问题。关键在于显式地为输入和输出指定UTF-8。最后，工作代码如下所示：

Process myProcess = new Process();

    myProcess.StartInfo.FileName = "C:\Path\to\php.exe";
    myProcess.StartInfo.Arguments = "C:\Path\to\purify.php";

    myProcess.StartInfo.UseShellExecute = false;
    myProcess.StartInfo.RedirectStandardOutput = true;
    myProcess.StartInfo.RedirectStandardInput = true;
    myProcess.StartInfo.StandardOutputEncoding = Encoding.UTF8;

    myProcess.Start();
    StreamWriter myStreamWriter = new StreamWriter(myProcess.StandardInput.BaseStream, Encoding.UTF8);

    String inputText;
    inputText = txtCodes.Text;

    if (inputText.Length > 0)
    {
        myStreamWriter.Write(inputText);
    }

    myStreamWriter.Close();

    labMsg.Text = myProcess.StandardOutput.ReadToEnd();


    myProcess.WaitForExit();

    myProcess.Close();
