[REG: 5.12 -> 5.13] Non English characters fail to render correctly

The following code renders the characters incorrectly. ( See qtbug85560-sanserif.png )

    Text {
        text: "Београд"
        renderType: Text.NativeRendering
        font {
            family: "sanserif"
        }
    }

The sample project is attached (QtBug85560.zip)

This appears to be a regression, as the text renders correctly when built and ran under 5.12.

Removing the "family" from the font causes the text to render correctly, as does giving the font a large pixelsize (>50)
