QT tcp发送接收解决乱码

if(tcpClients[i]->peerAddress().toString()==clientIP &&tcpClients[i]->peerPort()==clientPort)
                {
                    tcpClients[i]->write(ui->plainTextEdit_Send_Msg->toPlainText().toUtf8());//windows与linux之间数据传送
                   //  tcpClients[i]->write(ui->plainTextEdit_Send_Msg->toPlainText().toLocal8Bit());////fromLocal8Bit显示中文，解决乱码,windows之间
                     ui->plainTextEdit_Recv_Msg->appendPlainText(GetCurrentTimeStr()+" 发送："+ui->plainTextEdit_Send_Msg->toPlainText());
