Title:
  Wrong PDF standard fonts are replaced when fonts package "fonts-
  texgyre" is installed - PDFs are rendered with missing characters

Status in fontconfig package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  
  please see following bug report on freedesktop with screenshots:
  https://bugs.freedesktop.org/show_bug.cgi?id=79527

  When fonts package "fonts-texgyre" from the "texgyre" package is installed,
  all PDFs containing e.g. a reference to a "Helvetica" font, which is usually not installed on Ubuntu systems, fontconfig mages a very bad choice with one of the fonts supplied in fonts-texgyre (like "TeX Gyre Heros").

  The problem is, apparantly the texgyre fonts us a different naming
  style for some important glyphs (like greek characters contained in
  many mathematical documents), so that fontconfig cannot find them.

  See screenshots in abovementioned bugreport: 
  ==> PDF readers only display a blank space in this case, which has potentially disastrous results (there are six orders of magnitude difference between an Ampere current and a Microampere current e.g..).

  There is a likely explanation also unter this bugreport:

  ==> Please change the Ubuntu font configuration so that all those PDFs
  are displayed correctly.
