Is there any way to get key code?

Hi!
Egui uses virtual keyboard key codes to translate keyboard events to egui events. If a keyboard has multiple layouts I can check input for A-Z keys but not for '[' key for example.

Let's consider this code:

let events = ui.input().events.clone();
for event in &events {
    match event {
        egui::Event::Key{key, pressed, modifiers} => {
            println!("{:?} = {:?}", key, pressed);
        },
        egui::Event::Text(t) => { println!("Text = {:?}", t) }
        _ => {}
    }
}

It prints:

A = true
Text = "a"
A = false

I can check key 'A' by 'key' value.
But if I switch keyboard layout and press '[':

Text = "х"

Different output for different languages but I want my code to work the same way for any layout.

How can I get raw key code instead of egui::Event::Key?

I don't see it as egui:s job to communicate all input events (be it keyboard, joystick etc) to the user, but only those events that are relevant to a UI. I strain to think of a situation where a user interface (e.g. a web app) needs to be able to figure out if "the button left of the enter key" was pressed, no matter what keyboard layout was used. I also don't think the scancode is even available on web backends.

If you want low level control I suggest you use winit directly, like in https://github.com/emilk/egui/blob/master/egui_glow/examples/pure_glow.rs

Ok, web backend may not support scancodes but what about virtual keyboard key codes?
And one more thing. Is Egui supposed to support hot keys? Without using virtual keyboard it will be hard to handle the same hot key on different layouts ( for example Ctrl + ; )
