Font embedding not working due to GhostScript `-I` switch

[hooberton]

After using embed_fonts(), fonts are embedded but do not display correctly:

library(ggplot2)
library(extrafont)
#> Registering fonts with R

temp <- ggplot() +
  geom_text(aes(x = 1, y = 1, label = "Courier"), family = "Courier New") +
  geom_text(aes(x = 1, y = 0, label = "Whitney"), family = "Whitney Book") +
  geom_text(aes(x = 1, y = -1, label = "Gotham"), family = "Gotham Book")

pdf("before.pdf", height = 5 / 2.54, width = 10 / 2.54)
temp
grDevices::dev.off()
#> quartz_off_screen 
#>                 2
extrafont::embed_fonts("before.pdf")
pdftools::pdf_fonts("before.pdf")
#> # A tibble: 4 × 4
#>   name                  type   embedded file                                 
#>   <chr>                 <chr>  <lgl>    <chr>                                
#> 1 LYPKWD+CourierNewPSMT type1c TRUE     ""                                   
#> 2 VDRBSP+Whitney-Book   type1c TRUE     ""                                   
#> 3 ZYKQGV+Gotham-Book    type1c TRUE     ""                                   
#> 4 Helvetica             type1  FALSE    "/System/Library/Fonts/Helvetica.ttc"

Here I specify the location of the fontmap:

library(ggplot2)
library(extrafont)
#> Registering fonts with R

temp <- ggplot() +
  geom_text(aes(x = 1, y = 1, label = "Courier"), family = "Courier New") +
  geom_text(aes(x = 1, y = 0, label = "Whitney"), family = "Whitney Book") +
  geom_text(aes(x = 1, y = -1, label = "Gotham"), family = "Gotham Book")

pdf("after.pdf", height = 5 / 2.54, width = 10 / 2.54)
temp
grDevices::dev.off()
#> quartz_off_screen 
#>                 2
extrafont::embed_fonts("after.pdf", options = list("-sFONTMAP='/Library/Frameworks/R.framework/Versions/4.2-arm64/Resources/library/extrafontdb/fontmap/Fontmap'"))
pdftools::pdf_fonts("after.pdf")
#> # A tibble: 3 × 4
#>   name                  type     embedded file 
#>   <chr>                 <chr>    <lgl>    <chr>
#> 1 OIFJQI+CourierNewPSMT truetype TRUE     ""   
#> 2 TVYEXO+Whitney-Book   truetype TRUE     ""   
#> 3 MCGSWN+Gotham-Book    truetype TRUE     ""

This is the output before and after.

Here is some system and session info:

Is the GhostScript -I switch not working correctly?
