QML MultiEffect garbled error message

[Yihua Liu]

In my qml file, I write

TreeView {
id: treeView
property int lastIndex: -1
...
delegate: TreeViewDelegate {
id: viewDelegate
...
MultiEffect {
    id: iconOverlay
    anchors.fill: arrowIcon
    source: arrowIcon
    colorization: 1.0
    brightness: 1.0
    colorizationColor: {
        const isTable = viewDelegate.index === treeView.lastIndex && !viewDelegate.hasChildren;
        if (isTable) {
            return Qt.lighter(Colors.database, 3)
        }
        const isExpanded = viewDelegate.expanded && viewDelegate.hasChildren;
        return isExpanded ? Colors.color2 : Colors.database
    }
}
...
}
...
}

where in Colors.qml I defined

import QtQuick

pragma Singleton

QtObject {
    ...
    readonly property color database: "#383737"
    ...
}

When I run my program, the debugger shows error messages like
QML MultiEffect: �޷�ê�������Ǹ�����ͬ������Ŀ��
or
QML MultiEffect: ???ê???????????????????????

I have tried to link both Quick and QuickControls2 but the problem still occurs. I'm using Qt 6.8.0 with MSVC 2022 (AMD64).

Fixed by modifying arrowIcon
