Description
This repository contains a script to fetch various open source OpenType fonts
with a MATH table as well as the corresponding fonts to use for the surrounding
text (if any). The fonts are converted into WOFF (with zopfli compression) and
WOFF2 formats using
fonttools, which may perform additional
optimizations. It is expected that all the transformations preserve
Functional Equivalence
and so Reserved Font Names remain unchanged. The fonts are finally
packaged with
some documentation, a license and a mathfont.css stylesheet, so that you can
easily use them on your Web site. Some proprietary fonts as well as incomplete
open source fonts are also listed but they are not provided.
Warning
Note that only Gecko and WebKit have (more or less complete) support for MathML and the OpenType MATH table. The WOFF2 format is not supported by all web rendering engines. Also some (but not all) of the fonts provide old style numbers and calligraphic letters accessible via OpenType font features. Some CSS rules from the CSS Fonts Module Level are provided to help selecting the corresponding glyphs, but these are not implemented/enabled in all browsers yet. In general, it is recommended to try the most recent versions of browsers.
Using Math fonts on your Web site
Download the
zip archive.
Choose one family for your web site and place the corresponding subdirectory
somewhere.
Make your pages link to the mathfonts.css stylesheet. The MathML formulas
will then render with the specified font. It's good to make them consistent
with the surrounding text, especially for inline expressions. To do that,
use the htmlmathparagraph class, e.g. <body class="htmlmathparagraph">.
By default, the local fonts installed on the system will be used. For open
source fonts, Web fonts in WOFF2 or WOFF format will be used as a fallback.
Most families provide old style numbers in the text font. You can use them via
the oldstylenumbers class, e.g.
<span class="oldstylenumbers">0123456789</span>. Some of the math fonts also
provide calligraphic style for the script characters, that you can select
with the calligraphic class e.g.
<math><mi mathvariant="script" class="calligraphic">A</mi></math> or
equivalently <math><mi class="calligraphic">𝒜</mi></math>.
Build Instructions
You need GNU Core Utilities
(or equivalent on UNIX systems) as well as sed, grep, unzip, wget,
fonttools,
zopfli and
brotli. Type the following command
to build the font directories:
./configure
make
Use make clean to remove intermediary files and make distclean to remove
all the files that are not tracked on GitHub.
