I tried using QString::fromLocal8Bit() but it's the same because I'm printing the QByteArray as it is.
My code:
mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QWidget>
{
Q_OBJECT
//here are defined some variables
public:
~mainWindow();
void createUI();
void process();
private slots:
void ReadOutput
(int,
QProcess::ExitStatus);
};
#endif // MAINWINDOW_H
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QWidget>
class mainWindow : public QWidget
{
Q_OBJECT
//here are defined some variables
public:
mainWindow(QWidget *parent = 0);
~mainWindow();
void createUI();
void process();
QProcess *process = new QProcess(this);
private slots:
void ReadOutput(int, QProcess::ExitStatus);
};
#endif // MAINWINDOW_H

ReadAllStandardOutput() is returning empty characters if they are not recognised
