Gentium Plus - Font Features
Gentium Plus is an OpenType-enabled font family that supports the Latin, Cyrillic, and Greek scripts. It includes a number of optional features that may be useful or required for particular uses or languages. This document lists all the available features.
These OpenType features are primarily specified using four-letter tags (e.g. 'cv17'), although some applications may provide a direct way to control certain common features such as small caps. For more information on how to access OpenType features in specific environments and applications, see Using Font Features.
Please note that Graphite support has been removed in the current release, but continues to be available in the version 5 fonts. See our Previous Versions archive.
This page uses web fonts (WOFF2) to demonstrate font features and should display correctly in all modern browsers. For a more concise example of how to use Gentium Plus as a web font see GentiumPlus-webfont-example.html in the font package web folder. For detailed information see Using SIL Fonts on Web Pages.
If this document is not displaying correctly a PDF version is also provided in the documentation/pdf folder of the release package.
