This property file allows font names that are used in PDF documents but cannot be displayed in browsers or apps to be mapped. This occurs either when short forms of standard font names specific to PDF are used in the PDF document (these are already mapped), or when font names have been used that browsers and apps do not recognise when the PDF was generated (also includes an example).
