Erewhon-Math package ==================== ## Description `Erewhon-Math.otf’ is an Utopia based OpenType mathematical font. The mathematical symbols are borrowed or derived from Michel Bovani’s Fourier-GUTenberg package, Latin letters and digits are borrowed from Michael Shape’s Erewhon font. ## Contents * Erewhon-Math.otf OpenType Math font * Erewhon-Math-Bold.otf Bold variant * fourier-otf.sty LaTeX style file: replaces fourier.sty for LuaTeX/XeTeX * Erewhon-Math.pdf Documentation in PDF format * Erewhon-Math.ltx Source of Erewhon-Math.pdf * unimath-erewhon.pdf Modified version of unimath-symbols.pdf showing available Erewhon-Math symbols compared to LatinModern, STIXTwo, Erewhon, TeXGyrePagella, Libertinus and EBGaramond. * unimath-erewhon.ltx Source of unimath-symbols.pdf * README.md (this file) ## Installation This package is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, Erewhon-Math can be installed under TEXMFHOME or TEXMFLOCAL, f.i. Erewhon-Math.otf in directory texmf-local/fonts/opentype/public/erewhon-math/ and fourier-otf.sty in directory texmf-local/tex/latex/erewhon-math/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/erewhon-math/ Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL. Finally, make the system font database aware of the Erewhon Math font (fontconfig under Linux). ## License * The font `Erewhon-Math.otf’ is licensed under the SIL Open Font License, Version 1.1.

Option fulloldstyle added to fourier-otf.sty, this option was available with the original fourier-GUTenberg package. - Sub- and superscript placement corrected for bold calligraphic capitals. - Metrics changed for sans-serif and typewriter glyphs. * v0.52 - Over/underbrace: metrics of horizontal variants tuned. - Added glyphs \nleqqslant and \ngeqqslant (U+E09A, U+E09B). - Fixed "Style=" options in fourier-otf.sty (they didn't work for XeLaTeX). * v0.53 - fourier-otf.sty now loads realscripts for better superscripts. - Vertical variants of \mathslash, \backslash: slope corrected. - Added proportional digits and lnum, pnum features in math mode. - Added character variant (cv11) for \partial. * v0.54 - Delimiters’ sizes (), [] and {} now match those of the Erewhon text fonts. Bacward compatibility option (+ss09) added. - Slight correction to degree position on radicals. - Experimental Bold variant added. - Glyph Bbbsum.v1 (displaystyle) added. - Metrics of some italic capitals (H,M,N,U) corrected. * v0.55 - Fixed vertical variants of \Vert and \Vvert. - Added stretchable integral for U+222B (usable with luametatex). * v0.56 - Package now compatible with mathtools’ stretchable arrows. - \diagup and \diagdown moved from private area to U+27CB, U+27CD. * v0.60 - Metrics of all "under" arrows and harpoons corrected. - Most horizontal arrows and harpoons are now stretchable. * v0.61 - fourier-otf.sty: options handled by `l3keys` instead of `xkeyval` (requires a LaTeX kernel not older than 2022-06-01). - fourier-otf.sty: option "fulloldstyle" now applies to both text and maths fonts. - Fixed widths of under/overbraces variants. - Blackboard bold capitals added to Erewhon-Math-Bold.otf. * v0.62 - Erewhon-Math-Bold: seven glyphs added (U+2107, U+2126, U+2127, U+212B, U+2132, U+2141). * v0.63 - Bug corrections: large parentheses and integrals. --- Copyright 2019-2023 Michel Bovani, Daniel Flipo E-mail: michel (dot) bovani (at) icloud (dot) com daniel (dot) flipo (at) free (dot) fr
