Hebrew search in PDFs is backwards?

This is really, really bad.... from qt/src/gui/painting/qpainter.cpp, inside
void QPainter::drawText(const QPointF &p, const QString &str, int tf, int 
justificationPadding)

I see this code:
    QStackTextEngine engine(str, d->state->font);
    engine.option.setTextDirection(d->state->layoutDirection);
    engine.itemize();
    QScriptLine line;
    line.length = str.length();
    engine.shapeLine(line);
    int nItems = engine.layoutData->items.size();
    QVarLengthArray<int> visualOrder(nItems);
    QVarLengthArray<uchar> levels(nItems);
    for (int i = 0; i < nItems; ++i)
        levels[i] = engine.layoutData->items[i].analysis.bidiLevel;
    QTextEngine::bidiReorder(nItems, levels.data(), visualOrder.data());

Now... it seems like QTextEngine::bidiReorder()  does exactly what you want 
logical->visual. However... this class is defined inside qtextengine_p.h... 
which means this is not official API.

But, IMHO, even if it's not marked, you can open a bug report on this at 
Nokia's bug tracker, and they will handle it for Qt 4.8, maybe 4.7. Meanwhile, 
if the header is installed - abuse it. If it's not included - hack it inside 
your application

(*) I know that this will not be accepted at KDE's svn ...
