Unicode in TextInput not showing

[t0m.n]

Hi!
Running the following code, the Unicode char \u0003 only shows in the Text but not in the TextInput. Using a TextField instead of a TextInput also doesn't work.
Any hints on what I'm missing here?

This is Qt 5.12.5 on a raspberry Pi3.

Thanks!

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Layouts 1.12

Window {
    visible: true
    width: 640
    height: 480

    FontLoader { id: testfont; source: "qrc:/testfont.otf" }

    RowLayout {
        anchors.fill: parent

        TextInput {
            font.family: testfont.name
            font.pixelSize: 36
            color: "black"
            text: "\u0003" + "Test"
        }

        Text {
            font.family: testfont.name
            font.pixelSize: 36
            color: "black"
            text: "\u0003" + "Test"
        }
    }
}
