Displaying a UTF-8 and UTF-16 text in QTextEdit

[Zunneh]

Hello all,
i want to make a little program to convert String to UTF-8 or UTF-16 and then displaying it in QTextEdit,
However, everyTime i want to show the QByteArray in QTextEdit, the data is implicitly converted to QString,
For exemple when i write "hello world" , it must display "\x68\x65\x6c\x6c\x6f\x20\x77\x6f\x72\x6c\x64" but the data is implicitly converted and i get "hello world" again in my QTextEdit :

This is my code,

QString textFrom = ui->TXT_From->toPainText();
QTextCodec *codec = 0;
QByteArray encodedString;
QString DataAsString;

switch (ui->CMB_From->currentIndex()) {
    case  TextType::UTF8:
        qDebug() <<"From UTF8";
        codec = QTextCodec::codecForName("UTF-8");
        encodedString = codec->fromUnicode(textFrom);

        ui->TXT_To->setText(encodedString);

l

Thanks

If you want to show the bytes of a string instead the string you have to convert every char into it's bytes and convert them to printable chars (in your case it looks like you want to display the hex values). See QString::at() and QString::number().

@Christian-Ehrlicher is there another method to directly display the QByteArray into QString instead of display character one by one like you said because i wanna do many encoding value like :
TIS-620
TSCII
UTF-8
UTF-16
UTF-16BE
UTF-16LE
UTF-32
UTF-32BE
UTF-32LE

No, and I don't see why this should be needed. Simply iterate over your QByteArray and convert each char to a (hex)string.
