In QT 5.4 and C++ I try to decode a string that has unicode entities.
I have this QString:
QString string = "file\u00d6\u00c7\u015e\u0130\u011e\u00dc\u0130\u00e7\u00f6\u015fi\u011f\u00fc\u0131.txt";
I want to convert this string to this: fileÖÇŞİĞÜİçöşiğüı.txt
I tried QString
's toUtf8
and fromUtf8
methods. Also tried to decode it character by character.
Is there a way to convert it by using Qt?
Qt provides a macro called QStringLiteral for handling string literals correctly.
Here's a full working example:
#include <QString>
#include <QDebug>
int main(void) {
QString string = QStringLiteral("file\u00d6\u00c7\u015e\u0130\u011e\u00dc\u0130\u00e7\u00f6\u015fi\u011f\u00fc\u0131.txt");
qDebug() << string;
return 0;
}
As mentioned in the above comments, you do need to print to a console that supports these characters for this to work.
I have just tested this code:
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QString s = "file\u00d6\u00c7\u015e\u0130\u011e\u00dc\u0130\u00e7\u00f6\u015fi\u011f\u00fc\u0131.txt";
qDebug() << s.length(); //Outputs: 22
qDebug() << s; //Outputs: fileÖÇŞİĞÜİçöşiğüı.txt
return a.exec();
}
This is with Qt 5.4 on ubuntu, so it looks like your problem is with some OS only.
