This crate aims to be a robust, ergonomic, high performance library for reading
OpenType fonts. It is built on top of the
[read-fonts](https://github.com/googlefonts/fontations/tree/main/read-fonts)
low level parsing library and is also part of the
[oxidize](https://github.com/googlefonts/oxidize) project.

## Features

### Metadata

The following information is currently exposed:

* Global font metrics with variation support (units per em, ascender,
descender, etc)
* Glyph metrics with variation support (advance width, left side-bearing, etc)
* Codepoint to nominal glyph identifier mapping
    * Unicode variation sequences
* Localized strings
* Attributes (stretch, style and weight)
* Variation axes and named instances
    * Conversion from user coordinates to normalized design coordinates

Future goals include:

* Color palettes
* Embedded bitmap strikes

## Panicking

This library should not panic regardless of API misuse or use of
corrupted/malicious font files. Please file an issue if this occurs.

## The name?

Following along with our theme, *skrifa* is Old Norse for "write" or "it is
written." And so it is named.

## Safety

Unsafe code is forbidden by a `#![forbid(unsafe_code)]` attribute in the root
of the library.
