When I try to use geom_text on a pictogram where scale_label_pictogram was used, I get a "missing font box". This is the code from the example in the readme with pizza slices, fruit, and bread with a geom_text command to show the problem.

xdf %>%
  count(parts, wt = vals) %>%
  ggplot(aes(label = parts, values = n)) +
  geom_pictogram(n_rows = 10, aes(colour = parts), flip = TRUE, make_proportional = TRUE) +
  scale_color_manual(
    name = NULL,
    values = c("#a40000", "#c68958", "#ae6056"),
    labels = c("Fruit", "Sammich", "Pizza")
  ) +
  scale_label_pictogram(
    name = NULL,
    values = c("apple-alt", "bread-slice", "pizza-slice"),
    labels = c("Fruit", "Sammich", "Pizza")
  ) +
  coord_equal() +
  theme_ipsum_rc(grid="") +
  theme_enhance_waffle() +
  theme(legend.key.height = unit(2.25, "line")) +
  theme(legend.text = element_text(size = 10, hjust = 0, vjust = 0.75)) +
  geom_text(aes(x=5, y=5, label = "testing 1 2 3"))

I tried adding a font family aesthetic to the above to no avail (e.g. `family = "serif")

When I comment out scale_label_pictogram, geom_text works as expected.

xdf %>%
  count(parts, wt = vals) %>%
  ggplot(aes(label = parts, values = n)) +
  geom_pictogram(n_rows = 10, aes(colour = parts), flip = TRUE, make_proportional = TRUE) +
  scale_color_manual(
    name = NULL,
    values = c("#a40000", "#c68958", "#ae6056"),
    labels = c("Fruit", "Sammich", "Pizza")
  ) +
#  scale_label_pictogram(
#    name = NULL,
#    values = c("apple-alt", "bread-slice", "pizza-slice"),
#    labels = c("Fruit", "Sammich", "Pizza")
#  ) +
  coord_equal() +
  theme_ipsum_rc(grid="") +
  theme_enhance_waffle() +
  theme(legend.key.height = unit(2.25, "line")) +
  theme(legend.text = element_text(size = 10, hjust = 0, vjust = 0.75)) +
  geom_text(aes(x=5, y=5, label = "testing 1 2 3"))

When I include scale_label_pictogram and add the fontawesome family to the geom_text, I get a glyph.

xdf %>%
  count(parts, wt = vals) %>%
  ggplot(aes(label = parts, values = n)) +
  geom_pictogram(n_rows = 10, aes(colour = parts), flip = TRUE, make_proportional = TRUE) +
  scale_color_manual(
    name = NULL,
    values = c("#a40000", "#c68958", "#ae6056"),
    labels = c("Fruit", "Sammich", "Pizza")
  ) +
  scale_label_pictogram(
    name = NULL,
    values = c("apple-alt", "bread-slice", "pizza-slice"),
    labels = c("Fruit", "Sammich", "Pizza")
  ) +
  coord_equal() +
  theme_ipsum_rc(grid="") +
  theme_enhance_waffle() +
  theme(legend.key.height = unit(2.25, "line")) +
  theme(legend.text = element_text(size = 10, hjust = 0, vjust = 0.75)) +
  geom_text(aes(x=5, y=5, label = "testing 1 2 3", family = "FontAwesome5Free-Solid"))

Duplicate of #67 and #71, probably.

Here is an actual reprex for posteriority:

  vals = c(10, 20, 30, 6, 14, 40, 30, 20, 10),
  col = rep(c("blue", "black", "red"), 3),
  fct = c(rep("Thing 1", 3),
