How to save a file in Windows 1250 code

[TomASS]

Hi.

I have all my data in Utf8, but now I have to save a file in Windows1250 code. How to conversion a data from utf8 to windows 1250 and save file in windows 1250 code?

Have a look at QTextCodec in combination with QTextStream.

Could you give me an example, there is only examples to and from Unicode :/

[franz]

Those are the exact examples you need. toUnicode() returns a QString (QStrings are unicode), fromUnicode() returns a QByteArray, which is your target encoding.

Ok, thanks, and what with save file in windows 1250?

Now I have:

QString numer_fakt = "222";
        QString fileName = QFileDialog::getSaveFileName(this, tr("Zapisz plik"),numer_fakt+".epp",tr("Pliki wymiany danych (*.epp)"));
        if(fileName.size()==0) return;
        QFile file(fileName);
        if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
        return;
 
        QString dane = "Ę Ã“ Ą Ś Ł Ż Ź Ć Ń ę ó ą ś ł ż ź ć ";
        QTextCodec *codec = QTextCodec::codecForName("Windows-1250");
        QByteArray encodedString = codec->fromUnicode(dane);
 
        QTextStream out(&file);
        out.setCodec(codec);
        out << encodedString;
        file.close();

QString numer_fakt = "222";
        QString fileName = QFileDialog::getSaveFileName(this, tr("Zapisz plik"),numer_fakt+".epp",tr("Pliki wymiany danych (*.epp)"));
        if(fileName.size()==0) return;
        QFile file(fileName);
        if (!file.open(QIODevice::WriteOnly | QIODevice::Text))
        return;

        QString dane = "Ę Ã“ Ą Ś Ł Ż Ź Ć Ń ę ó ą ś ł ż ź ć ";
        QTextCodec *codec = QTextCodec::codecForName("Windows-1250");
        QByteArray encodedString = codec->fromUnicode(dane);

        QTextStream out(&file);
        out.setCodec(codec);
        out << encodedString;
        file.close();

To copy to clipboard, switch view to plain text mode 

what's next? in file I've got only ? ? ? ? sings :/

Change line 14 with

out << dane;

out << dane;

To copy to clipboard, switch view to plain text mode 

or replace lines 12-14 with

file.write(encodedString();

file.write(encodedString();

To copy to clipboard, switch view to plain text mode

Line 8 is tricky. You'd better specify the encoding it comes from:

QString dane = QString::fromUtf8("Ę Ã“ Ą Ś Ł Ż Ź Ć Ń ę ó ą ś ł ż ź ć ");

QString dane = QString::fromUtf8("Ę Ã“ Ą Ś Ł Ż Ź Ć Ń ę ó ą ś ł ż ź ć ");

To copy to clipboard, switch view to plain text mode 

If the source file is utf-8 encoded of course.
