XeLaTeX/LuaLaTeX package for using unicode/OpenType maths fonts

This package provides an implementation of Unicode/OpenType mathematics for XeLaTeX and LuaLaTeX.

While I am a little wary of encouraging people to use this package for production work, I understand that it has certain uses and am making it available for distribution. Your testing and feedback is essential to fill in the many gaps that I miss!

Please be aware that this package is undergoing continued development and the interface and functionality should not be considered completely stable. But the more the package is used the more stable it will become. (Things are generally working now; it is only minutiae that may change in the future.)

Unicode maths is currently supported by the following freely available fonts:

- Latin Modern Math (Bogusław Jackowski, Janusz M. Nowacki)
- TeX Gyre Bonum Math (B. Jackowski, P. Strzelczyk and P. Pianowski)
- TeX Gyre Pagella Math (B. Jackowski, P. Strzelczyk and P. Pianowski)
- TeX Gyre Schola Math (B. Jackowski, P. Strzelczyk and P. Pianowski)
- TeX Gyre Termes Math (B. Jackowski, P. Strzelczyk and P. Pianowski)
- DejaVu Math TeX Gyre (B. Jackowski, P. Strzelczyk and P. Pianowski)
- Asana Math (Apostolos Syropolous),
- STIX (STIpub), and
- XITS Math (Khaled Hosny),
- Libertinus Math (Philipp H. Poll and Khaled Hosny).
- Fire Math (Xiangdong Zeng).

These fonts are available under open source licences (the GUST Font License and Open Font Licence).

The following fonts are proprietary with OpenType maths support:

- Lucida Bright Math (Charles Bigelow and Kris Holmes)
- Cambria Math (Microsoft),
- Minion Math (Johannes Küster, typoma GmbH)

I’m always looking for new fonts to test with, so please let me know of any new releases.

Please see the PDF documentation for full details. A simple beginning is:

```
\usepackage{unicode-math}
\setmathfont{texgyrepagella-math.otf}
```

Most LaTeX math should still work after this. (Let me know if it doesn’t.) Furthermore, it will be in a different font.

As well as running XeTeX or LuaTeX, this package requires recent versions of the
`lm-math`

, `fontspec`

, `expl3`

, `xpackages`

, and `lualatex-math`

packages.

I write LaTeX code as a hobby and a passion, not as part of my day job. If you would like to say thanks, please consider a donation at: https://www.patreon.com/wspr
