Please show the code for your updatePaintNode().

How do you pass text into your program?

What encoding are you using?

QQuickTextNode *node = static_cast<QQuickTextNode *>(oldNode);
node->addTextLayout(layout->position(),
                            layout,
                            d->m_color,
                            QQuickText::Normal,
                            QColor(),
                            QColor(),
                            d->m_selectionColor,
                            d->m_selectedTextColor,
                            d->m_paragraphSelections[i].first,
                            d->m_paragraphSelections[i].second);
node->markDirty(QSGNode::DirtyGeometry);
return node;
