[SOLVED]Probem reading Chinese text files

musimbate

Hi,

I am trying to read from a txt file (in chinese) using this piece of code
@

QString filename="C:/Users/danil/Documents/iwhiteboard/学科.txt";

QFile file(filename&#41;;
     if (!file.open(QIODevice::ReadOnly | QIODevice::Text&#41;)
     {
         qDebug()<<"THE FILE COULD NOT BE OPENED....";
         return 0;
     }

     else
     {
         qDebug()<<"IT IS OPENED AND WE CAN READ IT...";

     QTextStream in(&file);
     while (!in.atEnd()) {
         QString line = in.readLine();
         myString.append(line);
     }

     file.close();
     in.flush();

     }

I suspect it has something to do with codecs but everything I have tried from the doc lead me to nothing so far.The filename comes from a QFileDialog in case somebody is wondering.

Any help would be appreciated.Thanks.

Hi, seems the problem is in your first statement.

Anyway, please tell us:

which Qt are you using Qt4 /Qt5，
which compiler are you using MSVC or not?

Thanks for the reply,
I am using Qt 4 and MSVC.Would you care to tell what is wrong with that statement?

You can given a try to

@
QString filename=QString::fromLocal8Bit("C:/Users/danil/Documents/iwhiteboard/学科.txt");
@

AFAIK,
If you are using VS2008SP1 + KB980263 or MSVC2010 or MSVC2013, you can use utf8 as your executable character set. If you are using MSVC2005 or MSVC2010, utf8 can not be used.

Thanks 1+1=2 ,
I was able to get this to work ,and the current solution is as follows in case somebody else faces the same problem:

@
//GET THE FILE NAME FROM A QFileDialog
filenames=dialog.selectedFiles();
filename=filenames.at(0);

//USE fromUtf8 ON THE filename
QByteArray byteArray = filename.toUtf8();
const char* cString = byteArray.constData();
QString codedFilename = QString::fromUtf8(cString);

//THIS WAS TO SEE WHAT IT GAVE ME
testLineEdit->setText(codedFilename);
QString myString;

QFile file(codedFilename);
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
{
//WE FALL HERE WHEN THE FILE FAILS TO BE OPENED
testLineEdit->setText(file.errorString());
return;
}
else
{
//AND HERE WHEN WE HAVE SUCCESSFULY OPENED IT.
testLineEdit->setText("opened");
}

  QTextStream in(&file);
  //MAKE SURE WHAT YOU READ IS UTF-8
    in.setCodec("UTF-8");
    while (!in.atEnd()) {
     QString line = in.readLine();
     myString.append(line);
     }
  testLineEdit->setText(myString);

file.close();
in.flush();
 //NOW myString CONTAINS TEXT YOU READ.
