Basically, I have a string like "Sam\xe2\x80\x99s phone"
and I want to convert that to be "Sam's phone"
.
What is the easiest way to do that in Qt or C++?
I could loop through every character and look for \x
, and convert all characters to hex values (except the two digits after every \x
), and then convert it to string but is there a better way?
EDIT:
void someFunction(int exitCode, QProcess::ExitStatus exitStatus){
QProcess *someQProcess = reinterpret_cast<QProcess*>(sender());
QString output = someQProcess->readAllStandardOutput();
QStringList data = output.split("\n");
parseScan(data);
}
void parseScan(QStringList data){
QStringList nameList;
for(int i = 2; i < data.size(); i++ ){
QStringList dataLine = data[i].split("\t");
if(dataLine.size() == 5){
QString name = dataLine[4]; // name is "Sam\xe2\x80\x99s phone"
}
}
}
Thanks
I think the problem comes from the way you read the standard output. Indeed, your standard output has a poor chance to be utf-8.
I tried to reproduce the same behavior with echo
:
QProcess *p = new QProcess();
p->start("echo \"Sam\xe2\x80\x99s phone\"", QProcess::ReadOnly);
p->waitForFinished();
/* Read without conversion: */
qDebug() << p->readAllStandardOutput();
// "Sam\xE2\x80\x99s phone\n"
/* Read with conversion: */
qDebug() << QString::fromLocal8Bit(p->readAllStandardOutput());
// "Sam’s phone\n"
