Using a different font could be an easy solution?

Not familiar with how multilingual font handling works but doesn't look like egui supports much out of the box. Here's a relevant issue on the egui repo: emilk/egui#3060

I found this method that may help https://docs.rs/egui/latest/egui/struct.Context.html#method.set_fonts
I'll play around and see if it is going to work.
