Qt Smtp Mail Sender - Outlook Encoder Problem

Hello I'm sending messages from my program but in Outlook the text seems bad shift.

        smt->sendMail("from", "to","DaxiClient - " + ui->cmbSubject->currentText(),
                      "<b>დასახელება:</b> " + ui->lnObjectName->text() + "<br>" +
                      "<b>ს/კ:</b> " + ui->lnSk->text() + "<br>" +
                      "<b>ტელეფონი:</b> " + ui->lnMobile->text() + "<br>" +
                      "<b>E-Mail:</b> " + ui->lnEmail->text() + "<br><br><br>" +
                      "<b>წერილი:</b> " + "<br>" +
                      ui->txtText->toPlainText().toHtmlEscaped().toUtf8());

void smtp::sendMail(const QString &from, const QString &to, const QString &subject, const QString &body, QStringList files)
{
    qDebug() << "sent begin";
    message = "To: " + to + "\n";
    message.append("From: " + from + "\n");
    message.append("Subject: " + subject + "\n");

    //Let's intitiate multipart MIME with cutting boundary "frontier"
    message.append("MIME-Version: 1.0\n");
    message.append("Content-Type: multipart/mixed; boundary=frontier\n\n");

    message.append( "--frontier\n" );
    //message.append( "Content-Type: text/html\n\n" );  //Uncomment this for HTML formating, coment the line below
    message.append( "Content-Type: text/html\n\n" );
    message.append(body);
    message.append("\n\n");

    if(!files.isEmpty())
    {
        qDebug() << "Files to be sent: " << files.size();
        foreach(QString filePath, files)
        {
            QFile file(filePath);
            if(file.exists())
            {
                if (!file.open(QIODevice::ReadOnly))
                {
                    qDebug("Couldn't open the file");
                    QMessageBox::warning( 0, tr( "Qt Simple SMTP client" ), tr( "Couldn't open the file\n\n" )  );
                        return ;
                }
                QByteArray bytes = file.readAll();
                message.append( "--frontier\n" );
                message.append( "Content-Type: application/octet-stream\nContent-Disposition: attachment; filename="+ QFileInfo(file.fileName()).fileName() +";\nContent-Transfer-Encoding: base64\n\n" );
                message.append(bytes.toBase64());
                message.append("\n");
            }
        }
    }
    else
        qDebug() << "No attachments found";

    message.append( "--frontier--\n" );

    message.replace( QString::fromLatin1( "\n" ), QString::fromLatin1( "\r\n" ) );
    message.replace( QString::fromLatin1( "\r\n.\r\n" ),QString::fromLatin1( "\r\n..\r\n" ) );

    this->from = from;
    rcpt = to;
    state = Init;
    socket->connectToHostEncrypted(host, port); //"smtp.gmail.com" and 465 for gmail TLS
    if (!socket->waitForConnected(timeout)) {
         qDebug() << socket->errorString();
     }

    t = new QTextStream( socket );
    t->setCodec("UTF-8");

t is QTextStream

what do you mean by "bad shift"?

Are your source files UTF-8 encoded?
Since you wrote your encoded text directly into the source file the encoding gets most probably messed up.

For example try QString::fromUtf8("\xE1\x83\x93\xE1\x83\x90\xE1\x83\xA1\xE1\x83\x90\xE1\x83\xAE\xE1\x83\x94\xE1\x83\x9A\xE1\x83\x94\xE1\x83\x91\xE1\x83\x90") for დასახელება instead and check if it's working.

Everything remains the same
