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](https://software.sil.org/fonts/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](https://software.sil.org/gentium/download/previous-versions).*

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](https://software.sil.org/fonts/webfonts).
