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 Pagella. Greek symbols were taken from the Math Pazo font by Diego Puga with the kind permission from the author to use his work with the GFL licence. The double struck font was 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 calligraphic alphabet was taken from the Odstemplik font (http://www.dafont.com/odstemplik.font) with the kind permission from the author to use his font with the GFL licence; * the fraktur script is excerpted from the renowned Euler family (http://en.wikipedia.org/wiki/AMS_Euler); * the sans serif alphabets are excerpted from another renowned font, DejaVu Sans (the DejaVu fonts are a font family based on the Bitstream Vera Fonts, released under a free license, http://dejavu-fonts.org/wiki/Main_Page); * and finally, the monospaced alphabet is taken from Latin Modern Mono Light Condensed (http://www.gust.org.pl/projects/e-foundry/latin-modern). 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. Recent changes (ver. 1.605 --> ver. 1.632) comprised mainly interline settings in OTF tables (HHEA and OS/2) and the correction of the unicode slots assigned to contour integrals (glyphs `clockwise contour integral', u+2232, and `anticlockwise contour integral', u+2233, used to have swapped slots). * * * 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.
