Binary package “libgs9-common” in ubuntu bionic

interpreter for the PostScript language and for PDF - common files

 GPL Ghostscript is used for PostScript/PDF preview and printing.
 Usually as a back-end to a program such as ghostview, it can display
 PostScript and PDF documents in an X11 environment.
 This package provides common architecture-independent files needed by
 the GPL Ghostscript library.
 By default, GPL Ghostscript uses a font from the fonts-droid package to
 approximate glyphs in PDFs for which the requested CJK TrueType font
 is missing. If the fonts-droid package is not installed, these glyphs
 will be rendered as bullets.
