Issue with printing Korean character using UTF-8

[M_31]

Hi All,

I have an issue with printing Korean character. my sample code is

@
//! I have given the input to QPlaintextEdit as 세 - where the codePoint is 49464 ( \uC138 ) and We can type this character using key t+p after changing the keyboard layout to Korean language.

QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));

QString str = ui->plainTextEdit->toPlainText().trimmed();
qDebug()<<"Value="<<str;

QByteArray ba = str.toUtf8();
qDebug()<<"ba="<<ba;
@

Output:
Value=(Non-printable character) 세
ba=(Non-printable character) 세

//! But If I watch the values on watch window ( Debug mode) it shows the value as "\140470" for str and "\354\204\270" for ba

Please provide your valuable input.

Note:
I am using Qt 4.8.0, QtCreatot 2.4.1

Thanks
