Did this start after 0.9 upgrade? Does it happen at the startup or later?

It seems that the root cause is an error with a TTF_ERR_MESHER error code in https://github.com/fetisov/ttf2mesh library. This happens only on some glyphs/characters on the Playpen Sans font (Bold only). For example, characters "1", "5" and "6" and "9" whereas other digit characters work ok.

I implemented a bit better error reporting at https://github.com/blaind/ttf2mesh-rs/pull/16/files but that doesn't really address the cause.

For bevy_text_mesh, I think the .unwrap() / panic at https://github.com/blaind/bevy_text_mesh/blob/main/src/mesh_data_generator.rs#L95 is not a good behavior. Possibly it should fallback with "?" character generated, and if that does not work then having either an empty space or some generic mesh (e.g. a cube)? Any thoughts on this?
