[SOLVED] QLineEdit and QLabel displaying the wrong japanese characters

[s3l3ctr]

Hello

What i'm doing is, opening a file that may contain unicode characters, then i read all the text from that file to a QString, then with some regexp i search for the data i'm interested in.
Now, the problem is, QLineEdit isn't displaying the correct text. By correct i mean i get a different unicode characters from what i'm expecting. It does the same with QLabel too. I tried to save back the read content to a text file to check whether it is wrong there or not, but it's ok that way. The QRegularExpressionMatch is ok too, because i saved the result directly into a text file and the result was good.

Some code
@
QString fileName = QFileDialog::getOpenFileName(0,tr("Open .osu file"),"../../","*.osu");
if(!fileName.isEmpty()){
ui->ucOsuFileNameText->setText(fileName);
QFile file(fileName);
file.open(QIODevice::ReadOnly);
QTextStream stream(&file);
QString fileContent = stream.readAll();
QRegularExpression regexp;
QRegularExpressionMatch regexpResult;
QStringList regexpList;
regexpList.append(_Scanner::artistRegexp);
regexpList.append(_Scanner::titleRegexp);
for(int i=0; i<regexpList.length(); ++i){
regexp.setPattern(regexpList[i]);
regexpResult = regexp.match(fileContent);
qDebug() << fileContent.length();
switch(i){
case 0: ui->ucArtistText->setText(regexpResult.capturedTexts().last());
break;
case 1: ui->ucTitleText->setText(regexpResult.capturedTexts().last());
break;
}
}
file.close();
}

What am i doing wrong? I read after the translations and codecs but i really didn't understand that, but i think, as QString supports unicode by default, it doesn't require any conversions.

Thank you for your answers.

Which encoding does the file use ? QTextStream can only automatically detect BOM for UTF-16 and UTF-32. If your file is something like UTF-8 then you need to set that codec on the stream before calling readAll() eg.
@
QTextStream stream(&file);
stream.setCodec("UTF-8");
QString fileContent = stream.readAll();

Thank you for the quick reply and also for the solution :) .
I set the codec as you mentioned and it worked, the file is in UTF-8 without BOM (as notepad++ says).
