fontconfig 2.11.94-0ubuntu1 (arm64 binary) in ubuntu xenial

 Fontconfig is a font configuration and customization library, which
 does not depend on the X Window System. It is designed to locate
 fonts within the system and select them according to requirements
 specified by applications.
 .
 Fontconfig is not a rasterization library, nor does it impose a
 particular rasterization library on the application. The X-specific
 library 'Xft' uses fontconfig along with freetype to specify and
 rasterize fonts.
 .
 This package contains a program to maintain the fontconfig cache
 (fc-cache), a sample program to list installed fonts (fc-list), a program
 to test the matching rules (fc-match) and a program to dump the binary
 cache files in string form (fc-cat). It no longer makes fonts managed by defoma
 available to fontconfig applications.
