I can't figure out how you are printing the string, but that is just Unicode:
#include <QString>
#include <QFile>
#include <QDebug>
int main(int argc, char **argv)
{
QString s = "\u05ea\u05e7\u05dc\u05d9\u05d8 \u05e9\u05e1\u05d9\u05de\u05dc \u05e9\u05d9\u05e0\u05d5\u05d9 \u05d1\u05e1\u05d2\u05e0\u05d5\u05df \u05dc\u05d3\u05e2\u05ea\u05d9 \u05d0\u05dd \u05d0\u05e0\u05d9 \u05d6\u05d5\u05db\u05e8 \u05e0\u05db\u05d5\u05df";
QFile file1("1.txt");
if (!file1.open(QIODevice::WriteOnly | QIODevice::Text))
return 1;
QTextStream out(&file1);
out << s << "\n";
qDebug() << s;
return 0;
}
If I compile and run it
g++ -lQtCore -I /usr/include/QtCore test.cpp
./a.out
I can see the printable characters both in the console debug output and in the file:
"תקליט שסימל שינוי בסגנון לדעתי אם אני זוכר נכון"
So you are probably doing something wrong or looking in the wrong direction, can you paste your code so we can help you better?
