These fonts are supported by all major operating systems (macOS, Windows, Linux-based, iOS, and Android), however the extent of that support depends on the individual OS and application.
Install the fonts by decompressing the .zip archive and installing the fonts using the standard font installation process for .ttf (TrueType/OpenType) fonts for your platform. For additional tips see the help page on Font installation.
These fonts do not include keyboards or other software for entering text. To type the symbols in these fonts use the keyboarding systems provided in your OS or use a separate utility. SIL’s Keyman provides keyboards for over 2000 languages and works on all major desktop and mobile platforms. For information on other keyboarding options see the overview at Keyboard Systems Overview (ScriptSource).
Rendering and application support
These fonts will work normally like any other fonts in most applications. If the writing system requires special diacritic positioning the application/OS will need to support OpenType.
These fonts also include extensive OpenType features for small caps, literacy forms, character alernates and language-specific preferences. For information on the specific features available in these fonts and how to use them see the documentation for each font family and the general information page on Using Font Features
Web font versions of these fonts (in WOFF and WOFF2 formats) are provided in the main download package. These can be copied to a web server and used as fonts on web pages. A very basic HTML/CSS demo page is also included. For more information on the options and techniques available for using these fonts on web pages see Using SIL Fonts on Web Pages.
These fonts are encoded according to The Unicode Standard. If you have text that uses a legacy, non-Unicode encoding there are tools that can help you convert that text for use with Unicode fonts. See Introduction to Text Conversion and Transliteration.
