Display French "ACCENT" from output QProcess

[Binary01]

Hii Forum,

I have a problem with the output of QProcess

m_process.start("ipconfig /all");
        if (!m_process.waitForStarted()) {
            qDebug() << "Error : " << m_process.errorString();
        }
        m_process.waitForFinished(-1); // will wait forever until finished
        output = m_process.readAllStandardOutput();
        ui->plainTextEdit_InfosConfig->setPlainText(output.toLatin1());

m_process.start("ipconfig /all");
        if (!m_process.waitForStarted()) {
            qDebug() << "Error : " << m_process.errorString();
        }
        m_process.waitForFinished(-1); // will wait forever until finished
        output = m_process.readAllStandardOutput();
        ui->plainTextEdit_InfosConfig->setPlainText(output.toLatin1());

To copy to clipboard, switch view to plain text mode 

I want to display the right symbol ( é not ?)

Well, maybe your system isn't configured to have UTF-8 as the shell process encoding.

Which you do assume here since you are assigning a QByteArray to a QString and that by default converts from UTF-8.

You can also convert to latin1 and then back to QString using UTF-8 again.

I would recommend using QString::fromLocal8Bit() for the "read" conversion.

Thnx for reply,

I tried to do :

m_process.waitForFinished(-1); // will wait forever until finished
        output = m_process.readAllStandardOutput();
        QByteArray str = output.toLatin1();
        ui->plainTextEdit_InfosConfig->setPlainText(QString::fromLocal8Bit(str));

m_process.waitForFinished(-1); // will wait forever until finished
        output = m_process.readAllStandardOutput();
        QByteArray str = output.toLatin1();
        ui->plainTextEdit_InfosConfig->setPlainText(QString::fromLocal8Bit(str));

How is defined variable output ? If it is QString You have to do something like this :

output = QString::fromLocal8Bit(m_process.readAllStandardOutput());
ui->plainTextEdit_InfosConfig->setPlainText(output);

output = QString::fromLocal8Bit(m_process.readAllStandardOutput());
ui->plainTextEdit_InfosConfig->setPlainText(output);

Yes,
output is QString :

QString output;

QString output;

To copy to clipboard, switch view to plain text mode 

I already tried this method

Not resolved

If it is On windows check with chcp command what is console code page.

[Binary01]

Cmd : chcp

Page de codes active*: 850

Page de codes active*: 850

To copy to clipboard, switch view to plain text mode 

[Lesiok]

Cmd : chcp

Page de codes active*: 850

Page de codes active*: 850

To copy to clipboard, switch view to plain text mode 

So try this

QTextCodec *codec = QTextCodec::codecForName("IBM850");
output = codec->toUnicode(m_process.readAllStandardOutput());
ui->plainTextEdit_InfosConfig->setPlainText(output);

QTextCodec *codec = QTextCodec::codecForName("IBM850");
output = codec->toUnicode(m_process.readAllStandardOutput());
ui->plainTextEdit_InfosConfig->setPlainText(output);

Good job @lesiok

It works, Thanks

[Lesiok]

Windows schizophrenia It uses two code pages : one for GUI and another for cmd. Qt's "local8bit" functions detects GUI cp so QString::fromLocal8bit is not working in this case.

[Binary01]

Hiii,

I tried the same code in other windows (64 bits), the program crash in :

QTextCodec *codec = QTextCodec::codecForName("IBM850");

QTextCodec *codec = QTextCodec::codecForName("IBM850");

To copy to clipboard, switch view to plain text mode 

Is there a way to standardize this method or using an other way ???

e.g : cmd chcp :

Page de codes active: 850

Page de codes active: 850

To copy to clipboard, switch view to plain text mode

So you ignore my suggestion and are wondering why the problem remains?
Maybe try to follow the suggestion before posting again?
