Currently egui only supports glyphs available in fonts that has been explicitly installed with ctx.set_fonts.

It would be great if there was a way for egui to tell it's integration "The user wanted to show a Chinese glyph, but no current font has support for that" and then have eframe respond by automatically finding such a font on the system, e.g. by downloading it.
