我的 node.js UDP 服务器的代码是

var PORT = 515;
var HOST = '127.0.0.1';

var dgram = require('dgram');
var server = dgram.createSocket('udp4');

server.on('listening', function () {
    var address = server.address();
    console.log('UDP Server listening on ' + address.address + ":" + address.port);
});

server.on('message', function (message, remote) {
    console.log(remote.address + ':' + remote.port +' - ' + message);

});

server.bind(PORT, HOST);

我的 C++ 客户端的代码是：

    WORD wVersionRequested = MAKEWORD(1, 1);
    WSADATA wsaData;
    int err = WSAStartup(wVersionRequested, &wsaData);

    if (err != 0)
    {
        return FALSE;
    }

    if ( LOBYTE( wsaData.wVersion) != 1 ||
        HIBYTE( wsaData.wVersion) != 1 ) 
    {
        WSACleanup();
        return FALSE;
    }

    // get the server address
    srvAddress.sin_addr.S_un.S_addr = inet_addr(GetProfileUdpHost());
    srvAddress.sin_family = AF_INET;
    srvAddress.sin_port = htons(GetProfileUdpPort());

int UdpSend(CString& content, SOCKADDR* address)
{
    SOCKET sockClient = socket(AF_INET, SOCK_DGRAM, 0);

    int result = sendto(sockClient, 
        content, 
        content.GetLength()+1, 
        0, 
        address, sizeof(SOCKADDR));

    closesocket(sockClient);

    return result;
}

当用户发送“中文”之类的字符时，nodejs UDP服务器收到“”。它得到无法识别的代码。我的 nodejs 代码的编码是 UTF-8 并且更改为 ANSI 是同样的问题。
