It's a bit more complicated than this when it comes to arabic. Arabic requires proper text shaping (right-to-left text). This is currently not supported by egui. emilk/egui#56

We can use egui-glyphon for this now

We can't actually, since this is for wgpu and may not work for the skia backend. we'll need to do something with cosmic-text directly
