# Idiqlat - Font Features

Idiqlat is an OpenType-enabled font family that supports the East Syriac style of the Syriac script. 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. 'ss01' or 'cv38'). For more information on how to access OpenType features in specific environments and applications, see Using Font Features.

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 Idiqlat as a web font see Idiqlat Webfont Example. For detailed information see Using SIL Fonts on Web Pages.
