[Tex/LaTex] State of Unicode math typesetting fonts


In a 2011 EuroBachoTeX talk, Ulrik Vieth discusses TeX unicode math fonts and their state of completeness.

He lists the following 4 fonts as (more or less) production-ready:

  • Cambria Math
  • Asana Math (Apostolos Syropoulos)
  • XITS Math (Khaled Hosny)
  • Latin Modern Virtual (Hans Hagen) [ConTeXt only]

And the following 4 fonts as "under development":

  • Neo Euler (Hermann Zapf, Khaled Hosny)
  • Lucida Math (Bigelow & Holmes, Khaled Hosny)
  • Latin Modern Math (GUST Foundry)
  • TeX Gyre Math (GUST Foundry)

As far as I can tell, Neo Euler development looks like it has stalled. The last update to the Neo Euler GitHub repository seems to have been 4 years ago.

Is the future of Neo Euler known? What about the development of the other unicode-math fonts?

Best Answer

The Latin Modern Math and TeX Gyre Math support projects are complete. Together, these fonts provide a total of 5 fonts for typesetting mathematics, all produced by the GUST e-foundry. Details can be found here.

That page lists an additional six fonts, produced by other foundries, which support the mathematics opentype extension, including 3 available from CTAN:

  • Asana Math;
  • Stix Math (v.2 expected 2016-12-31 according to barbara beeton;
  • Xits Math (contains a bold version);

and 3 proprietary:

  • Cambria Math;
  • Lucida Math (contains a demi bold version);
  • Minion Math by Johannes K├╝ster (contains a bold version).

GUST also provide this comparison document which covers all of the above fonts except for Minion Math.

That information is dated May 2014. What about new fonts? How can you evaluate their suitability?

  • I wrote this answer a while back to explain why a particular font combination did not work with unicode-math. In that answer, I compared that font combination with Latin Modern Math, which provides proper support. You can use my answer to assess the suitability of other fonts for use with unicode-math since I explain, basically, what a font needs in order to support typesetting maths using the interface this package provides. (The answer is: quite a lot.)


Here's a mini-demo of the 5 maths fonts provided by GUST:
