The math OTF fonts should contain a special table, MATH, described in the confidential Microsoft document "The MATH table and OpenType Features for Math Processing". Moreover, they should contain a broad collection of special characters (see "Draft Unicode Technical Report #25. UNICODE SUPPORT FOR MATHEMATICS" by Barbara Beeton, Asmus Freytag, and Murray Sargent III). In particular, math OTF scripts are expected to contain the following scripts: a basic serif script (regular, bold, italic and bold italic), a calligraphic script (regular and bold), a double-struck script, a fraktur script (regular and bold), a sans-serif script (regular, bold, oblique and bold oblique), and a monospaced script. The basic script is, obviously, TeX Gyre Bonum. The Greek symbols in TeX Gyre Bonum were excerpted from the Kerkis package (http://iris.math.aegean.gr/kerkis/) with the kind permission of the authors, Apostolos Syropoulos and Antonis Tsolomitis; in TeX Gyre Bonum Math, a few adjustments in the Greek alphabet were needed (such as adding four variants of kappa1: u03F0 -- regular, u1D6DE -- bold, u1D718 -- italic, u1D752 -- bold italic). The calligraphic script were created from scratch as well as the math extension, i.e., the main component of the font. Other scripts, however, are borrowed from other fonts (the current selection, however, may be subject to change): * The fraktur alphabets (regular and bold) is excerpted from the Leipziger Fraktur replica by Peter Wiegel ( http://www.peter-wiegel.de/Leipzig.html ) with the kind permission of the author. * The sans serif alphabets (regular, oblique, bold, and bold oblique) are excerpted from TeX Gyre Heros http://www.gust.org.pl/projects/e-foundry/tex-gyre/heros (actually, the sans serif bold Greek symbols were manually tuned). * The double struck script is excerpted from TeX Gyre Termes Math; in the future, we plan to replace it with the script having forms derived from TeX Gyre Bonum alphabet. * Finally, the monospaced alphabet is taken from TeX Gyre Cursor (see http://www.gust.org.pl/projects/e-foundry/tex-gyre/). Note that the members of all the mentioned alphabets, except the main roman alphabet, should be considered symbols, not letters; symbols are not expected to occur in a text stream; instead, they are expected to appear lonely, perhaps with some embellishments like subscripts, superscripts, primes, dots above and below, etc. To produce the font, MetaType1 and the FontForge library were used: the Type1 PostScript font containing all relevant characters was generated with the MetaType1 engine, and the result was converted into the OTF format with all the necessary data structures by a Python script employing the FontForge library. The TeX Gyre Math Project was launched and is supported by TeX USERS GROUPS (CS TUG, DANTE eV, GUST, NTG, TUG India, TUG, UK TUG). Hearty thanks to the representatives of these groups and also to all people who helped with their work, comments, ideas, remarks, bug reports, objections, hints, consolations, etc.
