https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Gentium is a typeface family designed to enable the diverse ethnic groups
+      around the world who use the Latin, Cyrillic and Greek scripts to produce
+      readable, high-quality publications. It supports a wide range of Latin and
+      Cyrillic-based alphabets.
+
+      The design is intended to be highly readable, reasonably compact, and
+      visually attractive. The additional ‘extended’ Latin letters are designed
+      to naturally harmonize with the traditional 26 ones. Diacritics are
+      treated with careful thought and attention to their use. Gentium Plus also
+      supports both polytonic and monotonic Greek.
+
+      This package contains the regular and italic styles for the Gentium Plus
+      font family, along with documentation.
