我使用自定义字体，主题切换按钮乱码了

[enomothem]

        let mut font_definitions = FontDefinitions::default();
        font_definitions.font_data.insert(
            "simsum".to_owned(),
            Arc::new(egui::FontData::from_static(include_bytes!("../assets/simsun.ttc"))),
        );

egui::TopBottomPanel::top("top_panel").show(ctx, |ui| {
            ui.horizontal(|ui|{
egui::widgets::global_theme_preference_switch(ui);

可能是因为字体缺少相应的 unicode 编码？

It might be because the font lacks the corresponding Unicode encoding?
