# Annapurna SIL - Resources

## Requirements

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.

## Installation

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.

## Keyboarding and character set support

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.

Various other means may be available for different operating system platforms to create additional input methods. Some suggestions are listed here: Keyboards and Tools.

See Character set support for details of the Unicode characters supported by these fonts.

## 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 character alternates and language-specific preferences. For information on the specific features available in these fonts see Font features.

If special font features are to be activated, the application will need to provide a way to turn on the feature or choose the feature setting. Details of current application support, and specific techniques for activating features, are on the Using Font Features help page.

## Web fonts

Web font versions of these fonts (in WOFF and WOFF2 formats) are available in the `web` folder. 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.

## Text conversion

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 an article on Encoding Conversion for an overview of available options.
