Custom fonts have vertical offset with unicode symbols

[woelper]

Egui default font with 0.21:

Noto sans with 0.19:

Noto sans with 0.21:

Although a bit hard to see, all symbols are offset in the y direction. I tried different fonts such as IBM plex, and they show this as well.

Describe the bug
Symbols are not vertically aligned with text if using a custom font.

To Reproduce
Steps to reproduce the behavior:

pub fn new(cc: &eframe::CreationContext<'_>) -> Self {
    let mut fonts = FontDefinitions::default();
    fonts.font_data.insert(
        "my_font".to_owned(),
        FontData::from_static(include_bytes!("../res/fonts/NotoSans-Regular.ttf")),
        // FontData::from_static(include_bytes!("../res/fonts/IBMPlexSans-Regular.ttf")),
    );
    fonts
        .families
        .get_mut(&FontFamily::Proportional)
        .unwrap()
        .insert(0, "my_font".to_owned());
    cc.egui_ctx.set_fonts(fonts);
    Default::default()
}

Actually after reading your post and trying Inter (which worked and is vertically aligned with symbols) I am not so sure any more if I just picked the wrong fonts. Noto and Plex are pretty common though and I wonder what they do differently.

There may be a "vertical offset" font attribute that egui ignores, and shouldn't. In any case, you can tweak the y-offset when you load your fonts using https://docs.rs/egui/latest/egui/struct.FontData.html#method.tweak

I've run into this using Roboto, and had to add a manual y offset in the font tweaks. Issue found when upgrading to v0.20.
