Android: Arabic numerals don't display

As can be seen with the following QML, Arabic numerals don't work properly on Android.

import QtQuick 2.2
import QtQuick.Window 2.1

Window {
    visible: true
    width: 360
    height: 360

    Text {
        text: qsTr("\u0661")
        anchors.centerIn: parent
    }
}

This should display the digit ١ but displays nothing. My guess is that this is related to font merging.
