Text widgets seem not to display correctly with Chinese character, here are some examples:

  1. English letter and Chinese character joined with \n, the Chinese character should be displayed as tofu.
slint::slint! {
    export component HelloWorld {
	width: 200px;
    height: 100px;
        Text {
            text: "hello,world.\n你好世界";
        }
    }
}
fn main() {
    HelloWorld::new().unwrap().run().unwrap();
}

2.All the Chinese character joint with \n, the character just in front of \n was missing.

slint::slint! {
    export component HelloWorld {
	width: 200px;
    height: 100px;
        Text {
            text: "你好\n世界";
        }
    }
}
fn main() {
    HelloWorld::new().unwrap().run().unwrap();
}

3.If add a space before \n, it could display well.

slint::slint! {
    export component HelloWorld {
	width: 200px;
    height: 100px;
        Text {
            text: "你好 \n世界";   // here is a  space in front of \n
        }
    }
}
fn main() {
    HelloWorld::new().unwrap().run().unwrap();
}

Thanks for the bug report. Looks like a series of bugs indeed. Could you enabling the Skia renderer and see if that works better for you? See https://releases.slint.dev/1.6.0/docs/slint/src/advanced/backend_winit and you might have to enable the renderer-skia feature on the slint crate (or enable SLINT_FEATURE_RENDERER_SKIA=ON if you're using CMake).
