font_fallback | R Documentation |
A fallback font is a font to use as a substitute if the chosen font does not contain the requested characters. Using font fallbacks means that the user doesn't have to worry about mixing characters from different scripts or mixing text and emojies. Fallback is calculated for the full string and the result is platform specific. If no font covers all the characters in the string an undefined "best match" is returned. The best approach is to figure out which characters are not covered by your chosen font and figure out fallbacks for these, rather than just request a fallback for the full string.
