How can i insert an emo::ji in a geom_text() for my ggplot?

[aito123]

Hello, i'm trying to insert an emoji on my donut ggplot but my emoji appears like a symbol (image attached), and not like the native: 😁

Is there a way to insert a type emoji object into the geom_text? because it can only be inserted using as.character(my_emoji)

Thanks very much.
