The first time you use a font, it may throw some warnings about unknown characters.
This should be harmless, but if it causes any problems, please report them.
Just test it on windows. Using cairo_pdf won't incur any warnings and the pdf file could be created properly, therefore you don't need to take the following steps to emb the fonts.

First, if you are running Windows, you may need to tell it where the Ghostscript program is, for embedding fonts. (See Windows installation notes below.)

# Adjust the path to match your installation of Ghostscript
Sys.setenv(R_GSCMD = "C:/Program Files/gs/gs9.05/bin/gswin32c.exe")

As the name suggests, `embed_fonts()` will embed the fonts:

CRAN has pre-compiled Windows and Mac OS X binaries.
For other platforms, and when installing from source, it will be compiled on installation, so you need a build environment on your system.


## Windows installation notes

In Windows, you need to make sure that Ghostscript is installed.

In each R session where you embed fonts, you will need to tell R where Ghostscript is installed.
For example, when Ghostscript 9.05 is installed to the default location, running this command will do it (adjust the path for your installation):

```R
Sys.setenv(R_GSCMD="C:/Program Files/gs/gs9.05/bin/gswin32c.exe")
```

## Resetting the font database

To reset the extrafont database, reinstall the extrafontdb package:

```R
install.packages("extrafontdb")
```
