The UNICODE-MATH package
========================
This package will provide a complete implementation of unicode maths for
XeLaTeX and LuaLaTeX.
While I am a little wary of encouraging people to use this package for
production work, I understand that it has certain uses and am making it
available for distribution. Your testing and feedback is essential to fill
in the many gaps that I miss!
Please be aware that this package is undergoing continued development and the
interface and functionality should not be considered completely stable. But
the more the package is used the more stable it will become. (Things are
generally working now; it is only minutiae that may change in the future.)
Unicode maths is currently supported by the following fonts:
- [Cambria Math][CM] (Microsoft),
- [Minion Math][MM] (Johannes Küster, typoma GmbH)
- [Latin Modern Math][LM] (Bogusław Jackowski, Janusz M. Nowacki)
- [TeX Gyre Pagella Math][PM] (Bogusław Jackowski, Janusz M. Nowacki)
- [Asana Math][AM] (Apostolos Syropolous),
- [Neo Euler][NE] (Khaled Hosny),
- [STIX][SM] (STI Pub), and
- [XITS Math][XM] (Khaled Hosny).
With the exception of Cambria Math, which is proprietry, the fonts above
are all freely available and released under open source licences
(the [GUST Font License][GFL] and [Open Font Licence][OFL]).
I'm always looking for new fonts to test with, so please let me know of any
new releases.

[SM]: http://www.aip.org/stixfonts/
[XM]: http://github.com/khaledhosny/xits-math
[GFL]: http://www.gust.org.pl/projects/projects/e-foundry/licenses/
[OFL]: http://scripts.sil.org/OFL
PACKAGE USAGE
-------------
Please see the PDF documentation for full details. A simple beginning is:
\usepackage{unicode-math}
\setmathfont{xits-math.otf}
Most LaTeX math should still work after this. (Let me know if it doesn't.)
Furthermore, it will be in a different font.
REQUIREMENTS
------------
As well as running XeTeX or LuaTeX, this package requires recent versions of the `fontspec`, `expl3`, `xpackages`, `filehook`, `ucharcat`, and `lualatex-math` packages.
MAINTENANCE
-----------
The current release version is available from CTAN:
> <http://tug.ctan.org/pkg/unicode-math>
Latest developmental and archived historical versions are available from Github:
> <http://github.com/wspr/unicode-math>
Please file bug reports with minimal examples:
> <http://github.com/wspr/unicode-math/issues>
CHANGE HISTORY
--------------
- v0.8c (2015/09/24)
* Add `\over(left/right)harpoon` as "wide" accents.
* Add RTL mathematics operators `\arabicmaj` and `\arabichad`, which correspond to `U+1EEF0` and `U+1EEF1`, resp.
* Remove `catchfile` package dependency.
* Update some internal names to match expl3 standards.
- v0.8b (2015/09/09)
* Bug fix: Use the "ucharcat" package to simplify some code that caused some headaches with \tl_rescan:nn.
- v0.8a (2015/08/06)
* Fix bug with \vert, \|, \(l/r)vert, etc., displaying with the wrong characters.
* Improve documentation to properly reflect changes in v0.8 and fix some broken examples.
* No longer reset catcodes of : and @ during \setmathfont .
* Fix remapping of alphabets (needed for Minion Math) in cases such as:
\setmathfont[range=bfit->it]{MinionMath-Bold.otf}
- v0.8 (2015/07/29) **Breaking changes in this update!**
* `\mathrm` (`\mathup`), `\mathit`, `\mathbf`, `\mathsf`, and `\mathtt` revert to their traditional LaTeX meanings; they are set up to match their equivalent text fonts unless specifically set using `\setmathrm` and friends from `fontspec` or the new `\setmathfontface` in `unicode-math`. These commands should be used for *multi*-letter identifiers.
* New "symbol" commands have been added, `\symrm` (`\symup`), `symit`, ..., to replace the behaviour of the old commands. These should be used for *single*-letter identifiers. See the package documentation for more detail on these and related commands.
* Package options `mathit=sym`, `mathbf=sym`, etc., reverse the changes above to revert to pre-v0.8 behaviour for `\mathXYZ`. Regardless of package option, `\symXYZ` always maps to symbols and `\mathtextXYZ` is provided for the traditional `\mathXYZ` font switch.
* New command `\setoperatorfont` to set the font used for commands such as `\sin` and `\cos`. Usage: `\setoperatorfont\mathbf` or any command defined with `\setmathfontface`.
* Traditional LaTeX `\DeclareMathAlphabet` now works again for legacy font-loading packages.
* Commands defined to "force" Greek letters with `\upbeta` and `\itbeta`, etc.
* Assorted bug fixes and minor changes.
- v0.7e (2014/06/30)
* No longer assume fixltx2e has been loaded.
* Some ascii math symbols have been renamed with a \math... prefix, such as \mathquestion.
* Assume latest luaotfload is being used; no need for a separate unicode-math.lua script.
* Assorted typos and minor bugs.
- v0.7e (2013/05/04)
* Track luaotfload updates.
- v0.7d (2013/03/16)
* More expl3 changes missed first time around. (Sorry again.)
- v0.7c (2013/02/25)
* The Latin Modern math font name changed TWICE. Only caught the first one.
Sorry for any inconvenience caused.
- v0.7b (2013/02/22)
* Keep in sync with Latin Modern Math font name change.
* Keep in sync with expl3 changes.
- v0.7a (2012/07/28)
* Keep in sync with expl3 changes.
- v0.7 (2012/05/30): The TeX Live 2012 release.
* Most changes (and all significant ones) in this release thanks to Khaled
Hosny, who is now credited as an author of the package.
* Many improvements for XeTeX support to take advantage of the new engine
(v0.9998) in TL2012.
* As a result, `\resetmathfont` is no longer required.
* Improve `\not` to use pre-combined glyphs where possible.
* LM Math is loaded by default.
* Support bottom accents.
* And add `\wideutilde`.
* The ‘symbols’ document is somewhat better organised and contains
information on whether a symbol is defined in plain TeX or amssymb.
* Various other minor fixes and additions:
* `\underleftrightarrow` added for fonts that support it.
* Don’t overwrite mathtool’s `\overbracket` and `\underbracket`.
* Bug in `[range=...]` parsing fixed.
* Add `\longdivision`.
* Add `\lgroup` and `\rgroup`.
* Fix ‘moustache’ delimiters.
* `\openbox` renamed to `\mathvisiblespace`, since it is already defined
in amsthm as an empty box.
- v0.6a (2011/09/19)
* Always a bug that slips through the cracks! Fixes `\left.` and `\right.`
* Add experimental package option `warnings-off=...` which allows warnings
to be suppressed on an individual basis.
- v0.6 (2011/09/18)
* Keep in sync with fontspec internals
(sorry for the small delay where things were broken)
* Keep in sync with expl3 deprecated functions
* Math versions (finally) implemented; can now change maths fonts
mid-document without reinitialising everything
(thanks to Ulrike Fischer and Ulrik Vieth)
* Symbols file `unimath-symbols.pdf` now uses maths versions to compare
all of the OpenType maths fonts I currently have access to
* Over- and under- braces, brackets, and parentheses now work in XeTeX
(thanks to Claudio Beccari)
* Many internal changes, including a re-write of the `range` feature;
it should now be faster and more robust
* Tentative programmer's interface for querying the current math style:
`\l_um_mathstyle_tl`.
* Remove (outdated) interaction with beamer; you must specify
`professionalfonts` manually for now
* Quieten the console output when loading maths fonts with incomplete maths
style coverage
* Synonym added: `\lnot` -> `\neg`
* Two added Unicode symbols (names tentative): `\blanksymbol` and `\openbox`
(thanks to Apostolos Syropoulos)
* Fixed literal sub-/super-script input.
- v0.5e (2011/07/31)
* Fix forward compatibility clash with deprecated expl3 functions (sorry)
* Command names are now `\protected`; this makes them safe to use in moving
arguments and so on
* Similarly to the change in v0.5c, the main math font is now loaded in
math family zero (equiv. to LaTeX's `operators` math font)
* `\mathring` added
* Ensure that a math font has been selected in order to prevent problems
in minimal documents (this will be unnecessary when the OpenType LM math
font is released)
* Documentation for which was which of epsilon/varepsilon was backwards!
(thank to Rasmus Villemoes for pointing this out)
* Spurious `\upUpsilon` removed (the one at U+03A5 is now the correct one)
* Typo when defining `\dprime` fixed
(thanks to Ulrik Vieth for these last two)
* Fix the math class of `\modtwosum`; it is now a large operator
(thanks to Michael Ummels)
* Move several LuaTeX-related patches to the `lualatex-math` package
* Fixed mathtool's `\cramped` in XeLaTeX usage
- v0.5d (2011/01/30)
* Assorted improvements to LuaLaTeX support, including non-growing accents
available in LuaTeX v0.65 and later
* Improved behaviour with reading and using maths font dimensions
* Better compatibility with legacy maths packages and environments
(always more worked needed, though)
* Fix the default setting for "vargreek-shape"
- v0.5c (2010/09/27)
* Fix a long-standing bug in XeLaTeX in which the "master" math
families 2 and 3 weren't being set; hence fraction rules and many other
parameters were not being set correctly
* Stay in sync with internal fontspec changes
- v0.5b (2010/09/19): Tune-up
* Added missing symbols/synonyms:
\diamond \smallint \emptyset \hbar \backepsilon \eth
* \overline works for LuaLaTeX
* Fix \slash; previously, it overwrote the text definition
* \vartriangle now has the correct math class
- v0.5a (2010/07/14): TeX Live 2010 release
* Numerous documentation improvements
* Bug fix against stray catcode changes
* Add `\mathcal` and `\mathbfcal` as distinct from the Script style;
these are only supported by the XITS fonts at present
* Small changes to the range of symbols offered (especially note that `\ac`
is now `\invlazys` to avoid acronym package clash)
* Superscripts are allowed after primes (as they should be)
* Numerous LuaLaTeX improvements, including roots and over/under braces.
- v0.5 (2010/06/03): Initial CTAN release
