Why aren't emojis rendering properly in ggplot?

I have failed many times to incorporate emojis into ggplot and am including a basic example below where I'm simply trying to add an emoji to both axes titles on a blank plot. Grateful for any and all help:

library(tidyverse)
#remotes::install_github("hadley/emo")
library(emo)

ggplot() +
  xlab(paste0('Mileage', emo::ji("fuel_pump"))) +
  ylab(paste0('Vehicle', emo::ji("car"))) +
  theme(text = element_text(family = "Trebuchet MS"))

This yields:

I also tried using the emojifont package.

library(emojifont)

ggplot() +
  xlab(paste0('Mileage', emojifont::emoji("fuel_pump"))) +
  ylab(paste0('Vehicle', emojifont::emoji("car"))) +
  theme(text = element_text(family = "Trebuchet MS"))

With this second attempt, not only do the emojis not render properly, but I receive the following warning and the font family I selected is replaced with something generic: "1: In grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : font family 'Trebuchet MS' not found, will use 'wqy-microhei' instead"

Finally, including sessionInfo() below:
