Some symbols are in Unicode but +are included because they are variants that may look better in some +applications. Logic tends not to have the complex layouts that is common for +more general mathematics, but has different requirements for readability. +This font is intended to complement, but not replace the AMS STIX2 fonts. +However, it may used with any mathematical font since it does not replace or +redefine any symbols. + +This is an OpenType font where all of the symbols (more than 4,000) other than +the ASCII codepage are in the private use area. As such, the package requires +XeLaTeX or LuaLaTeX. Not all of those symbols are directly exported, since +there are many variants present for possible future use. While only the +OpenType font file is usable for LaTeX, the .ttf, .woff, .woff2 and .eot font +files are also supplied in this distribution. + +Other than many miscellaneous symbols, there are a large number of arrows, +geometrical symbols, Knot drawing symbols, 64 stretchy delimiters plus a +stretchy binding bar, of which 56 are fully stretchable. The remaining 8 are +stretchy up to 5 times the original size. Some of the delimiters are present +in Unicode, but their design in STIX2 does not work as well for logic. In +particular, STIX2 delimiters tend to not extend as far below the baseline +and above the baseline as would be desirable. Also, some STIX2 delimiters +take more horizontal space than is necessary. + +There are twenty scripts, each of which (except for the two Greek scripts) +have matching numeric, lower case and upper case glyphs. All symbols in this +font are designed to be compatible with the STIX2 mathematical font by AMS. +Some of these scripts overlap the Unicode math scripts, but are not intended +to be replacements for those. Unicode does not include everything for a specific +script -- digits or lower case may be missing, or even individual letters +(although that may have changed). That is an issue when using a script for +variable naming. Some script variants are omitted. Many of those variants are +useful in logic. The scripts included are sans serif, slab serif, normal serif +(each of these has upright, italic, bold and bold italic versions) as well as +a calligraphic font, blackboard, fraktur (upright and bold), monospace, +monospace italic with normal serif, and Greek (upright and italic). + +Licenses: + + The logix font is licensed under the Open Font License, version 1.1 or + later. + + The font contains modified serif alphanumeric and Greek symbols from the + STIX2 fonts, Copyright © 2001-2016 by the STI Pub Companies (OFL license + 1.1), modified slab serif alphanumeric symbols from the Zilla Slab fonts, + Copyright © 2017 The Mozilla Foundation (OFL license 1.1) and modified sans + serif alphanumeric symbols from the Clear Sans font, Copyright © 2012 Intel + Corporation (Apache License 2.0). + + The OFL license can be found at: http://scripts.sil.org/OFL. + + The Apache license can be found at: http://www.apache.org/licenses/LICENSE-2.0.html. + + This file, the documentation and the logix.sty file are distributed and/or + modified under the conditions of the LaTeX Project Public License, either + version 1.3 of this license or (at your option) any later version.
