    Default Problem with utf8

    when I copy a QString with spanish words then I get difficulties with some letters:

    As example, french is ok.
    input: Il aura bientôt réglé ce poste.
    output: Il aura bientôt réglé ce poste.

    but spanish, not.
    input: Su anulación llegó demasiado tarde.
    output: Su anulaci�n lleg� demasiado tarde.

    the code that I use is:

    QStringList word = oneLine.split('#');

    for (int i = 1; i < word.size(); ++i)
    {
    temp =word.at(i);
    if(!temp.isEmpty())
    output += temp+ '\n';
    }

    How I can copy the words correctly?
    My os is kubuntu 18.04 and Qt 5.11, standard utf8
    Thanks

    1. What is oneLine ? How it is filled ?
    2. What is temp and output ?

    Show real code.

    I include the cpp-file.
    Dialog:ialog(QWidget *parent)
    : QDialog(parent)
    {
    inLabel = new QLabel(tr("Input: "));
    inEdit = new QLineEdit(tr("/home/sp75/sp24.txt"));


    outLabel = new QLabel("Output:");
    outEdit = new QLineEdit("/home/sp75/sp24_mo1.txt");

    QHBoxLayout *inLayout = new QHBoxLayout;
    inLayout->addWidget(inLabel);
    inLayout->addWidget(inEdit);

    QHBoxLayout *outLayout = new QHBoxLayout;
    outLayout->addWidget(reiheLabel);
    outLayout->addWidget(reiheEdit);

    showText = new QTextEdit;

    QHBoxLayout *btnLayout = new QHBoxLayout;
    untenLayout->addWidget(okButton);
    untenLayout->addStretch();
    untenLayout->addWidget(endButton);

    connect(okButton, SIGNAL(clicked()), this, SLOT(loadTextFile()));
    connect(endButton, SIGNAL(clicked()), this, SLOT(close()));

    QVBoxLayout *mainLayout = new QVBoxLayout;
    mainLayout->addLayout(inLayout);
    mainLayout->addLayout(outLayout);
    mainLayout->addWidget(showText);
    mainLayout->addLayout(btnLayout);
    setLayout(mainLayout);
    }

    void Dialog::loadTextFile()
    {
    QString rowTxt, txtFileStr;
    txtFileStr =inEdit->text();
    QFile inputTxtFile(txtFileStr);

    if(!inputTxtFile.open(QIODevice::ReadOnly))
    qFatal( "Could not open the file" );

    QTextStream inTxt(&inputTxtFile);
    rowTxt.append(inTxt.readAll());
    inputTxtFile.close();

    QStringList lineTxt = rowTxt.split('\n');

    QString outStr;
    outStr = outEdit->text();
    QFile outFile(outStr);
    if(!outFile.open(QIODevice::WriteOnly | QIODevice::Text))
    return;
    QTextStream out(&outFile);

    QString oneLine, word, temp;

    for (int i = 0; i < lineTxt.size(); ++i){
    lineZeile = lineTxt.at(i);
    if (!lineZeile.isEmpty()){
    oneLine = lineTxt.at(i);

    QStringList word = oneLine.split('#');

    for (int i = 1; i < word.size(); ++i)
    {
    temp =word.at(i);
    if(!temp.isEmpty())
    output += temp+ '\n';
    }

    }
    }

    showText->append(output);
    showText->setUndoRedoEnabled(false);
    showText->setUndoRedoEnabled(true);
    out << output;
    }
    sp24.txt

    OK. And where is the problem : in showText or in out file ?
    What is the code page of the sp24.txt file ?

    The error is in both showText and outfile.
    According to kubuntu the sp24.txt is utf8 coded.
    It seems that QtCreator refuses to open the textfile when it is saved in different code.

    Try to add this line :
    Qt Code:
    1. inTxt.setCodec("UTF-8");
    To copy to clipboard, switch view to plain text mode 
    before readAll().
    From QTextStream doc : By default, QTextCodec::codecForLocale() is used.

    And please use [CODE] tag for code.

    I found the error.
    The text was written with kwrite, it seems that it is not reliable.
    I copied the text with kate and the problems disappeared.
    thanks
