+\begin{document}
+\maketitle
+
+\section{What is \FOTF{}?}
+
+\FOTF{} is an Utopia based Opentype mathematical font.
+The mathematical symbols and Greek letters are borrowed or derived from
+Michel Bovani’s \FGUT, Latin letters and digits are borrowed from
+Michael Shape’s Erewhon font.
+
+It requires LuaTeX or XeTeX as engine and the \pkg{unicode-math} package%
+\footnote{Please read the documentation \file{unicode-math.pdf}.}.
+
+It is meant to be used with Utopia based Opentype text fonts like {Erewhon}.
+For \FGUT{} users who want to switch to LuaLaTeX or XeLaTeX, the
+file \file{fourier-otf.sty} can be used as a replacement of \file{fourier.sty}.
+
+Please note that the current version (\version) is \emph{experimental,
+do expect metrics and glyphs to change} until version 1.0 is reached.
+
+Comments, suggestions and bug reports are welcome!
+
+\section{Usage}
+
+\subsection{Calling \cmd{setmathfont}}
+
+A basic call for \FOTF{} would be:
+\begin{verbatim}
+\usepackage{unicode-math}
+\setmathfont{Erewhon-Math.otf} % Call by file name or
+\setmathfont{Erewhon Math} % Call by font name
+\end{verbatim}
+this loads \FOTF{} as math font with the default options, see
+subsections~\vref{ssection-um}, \vref{ssection-cv} and~\vref{ssection-ss}
+for customisation.
+
+Please note that the three sets of text fonts have to be chosen separately,
+f.i.:
+\begin{verbatim}
+\setmainfont{Erewhon} % rm
+\setsansfont{Cabin}[Scale=MatchLowercase] % sf
+\setmonofont{Inconsolatazi4}[Scale=MatchLowercase] % tt
+\end{verbatim}
+otherwise you would get Latin Modern for text fonts.
+
+\subsection{Calling \pkg{fourier-otf.sty}}
+
+As an alternative to load \FOTF{} --\emph{this is the recommended way}--
+you can type:\\[.5\baselineskip]
+\verb+\usepackage[ +\textit{options}
+\footnote{Possible \textit{options} are \opt{loose} or any of the options
+ described below for \cmd{setmainfont}.}%
+\verb+ ]{fourier-otf}+\\[.5\baselineskip]
+it also loads \pkg{unicode-math} with the default options and and sets
+\file{Fourier Math} as Math font but does a bit more:
+\begin{enumerate}
+\item it checks at \verb+\begin{document}+ if packages \pkg{amssymb} or
+ \pkg{latexsym} are loaded and issues warnings in case they are;
+\item it provides aliases for glyphs named differently in Unicode, so that
+ \pkg{latexsymb} or AMS names are also available;
+\item it loads \pkg{fourier-orns.sty}, providing many text ornaments;
+\item it defines specific Math characters like \showmchar{Bbbbackslash},
+ \showmchar{varemptyset}, \linebreak[4]
+ \showmchar{parallelslant},
+ \showmchar{shortparallelslant}, etc.;
+\item it reduces spacing in math mode: \cmd{thinmuskip}, \cmd{medmuskip}
+ and \cmd{thickmuskip} are reduced as in \file{fourier.sty}.
+% \verb+\thinmuskip=2mu+,\\
+% \verb+\medmuskip=2.5mu plus 1mu minus 2.5mu+,\\
+% \verb+\thickmuskip=3.5mu plus 2.5mu+.\\
+ The option \opt{loose} disables these settings.
+\end{enumerate}
+
+
+\section{What is provided?}
+
+\FOTF{} provides all glyphs supplied by \FGUT{} plus all glyphs available in
+the \pkg{amssymb} and \pkg{latexsym} packages and many more. Therefore, these
+two packages \emph{should not} be loaded as they might override \FOTF{} glyphs.
+
+Sans-serif, typewriter and fraktur styles are borrowed from Latin Modern fonts.
+See in section~\vref{ssec-math-alphabets} how to choose
+from other Math fonts for these styles.
+
+A full list of available glyphs is shown in file \file{unimath-erewhon.pdf}.
+
+\subsection{Upright or slanted?}
+\label{ssection-um}
+
+Package \pkg{unicode-math} follows \TeX{} conventions for Latin and Greek
+letters: in math mode, the default option (\opt{math-style=TeX}) prints
+Latin letters $a$…$z$ $A$…$Z$ and lowercase greek letters $\alpha$…$\omega$
+slanted (italic) while uppercase greek letters $\Alpha \Beta \Gamma$…$\Omega$
+are printed upright.
+This can be changed by option \opt{math-style} as shown in
+table~\vref{math-style}.
+
+\begin{table}[ht]
+ \centering
+ \caption{Effects of the \opt{math-style} package option.}
+ \label{math-style}
+ \begin{tabular}{@{}>{\ttfamily}lcc@{}}
+ \hline
+ \rmfamily Package option & Latin & Greek \\
+ \hline
+ math-style=ISO & $(a,z,B,X)$ & $\symit{(\alpha,\beta,\Gamma,\Xi)}$ \\
+ math-style=TeX & $(a,z,B,X)$ & $(\symit\alpha,\symit\beta,\symup\Gamma,\symup\Xi)$ \\
+ math-style=french & $(a,z,\symup B,\symup X)$ & $(\symup\alpha,\symup\beta,\symup\Gamma,\symup\Xi)$ \\
+ math-style=upright & $(\symup a,\symup z,\symup B,\symup X)$ & $(\symup\alpha,\symup\beta,\symup\Gamma,\symup\Xi)$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+Bold letters are printed upright except lowercase Greek letters
+which are slanted (the default option is \opt{bold-style=TeX}). This can be
+changed by option \opt{bold-style} as shown in table~\vref{bold-style}.
+
+\begin{table}[ht]
+ \centering
+ \caption{Effects of the \opt{bold-style} package option.}
+ \label{bold-style}
+ \begin{tabular}{@{}>{\ttfamily}lcc@{}}
+ \hline
+ \rmfamily Package option & Latin & Greek \\
+ \hline
+ bold-style=ISO & $(\symbfit a, \symbfit z, \symbfit B, \symbfit X)$ & $(\symbfit\alpha, \symbfit\beta, \symbfit\Gamma, \symbfit\Xi)$ \\
+ bold-style=TeX & $(\symbfup a,\symbfup z,\symbfup B,\symbfup X)$ & $(\symbfit\alpha, \symbfit\beta,\symbfup \Gamma,\symbfup \Xi)$ \\
+ bold-style=upright & $(\symbfup a,\symbfup z,\symbfup B,\symbfup X)$ & $(\symbfup \alpha,\symbfup \beta,\symbfup \Gamma,\symbfup \Xi)$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+Other possible customisation: $\nabla$ is printed upright and $\partial$ is
+printed slanted by default, but \opt{nabla=italic} and
+\opt{partial=upright} can change this.
+
+All these options are offered by the \pkg{unicode-math} package but they can
+be added to the \cmd{setmathfont} call%
+\footnote{IMHO it is easier to add \emph{all options} to the \cmd{setmathfont}
+ command.}, for example:
+
+\verb+\setmathfont{Erewhon Math}[math-style=french,partial=upright]+\\
+will print for the code
+\begin{verbatim}
+\[ \frac{\partial f}{\partial x} = \alpha \symbf{V} + a\nabla\Gamma
+ + \symbf{\beta}\symbf{M} \]
+\end{verbatim}
+\setmathfont{Erewhon Math}[math-style=french,partial=upright]
+\[\frac{\partial f}{\partial x} = \alpha \symbf{V} + a\nabla\Gamma +
+ \symbf{\beta}\symbf{M} \]
+while the default settings would print
+\setmathfont{Erewhon Math}[math-style=TeX,partial=italic]
+\[\frac{\partial f}{\partial x} = \alpha \symbf{V} + a\nabla\Gamma +
+ \symbf{\beta}\symbf{M} \]
+
+If your text editor is able to handle greek letters or math symbols, they can
+be entered in the code instead control sequences (i.e.
+$\symup{α}$, $\symup{β}$, $\symup{Γ}$,… for \cmd{alpha}, \cmd{beta},
+\cmd{Gamma},…).
+
+\subsection{Character variants}
+\label{ssection-cv}
+
+\FOTF{} provides eleven ``Character Variants’’ options to choose between
+different glyphs for Greek characters and some others, see table~\vref{cv}
+for the full list.
+
+For instance, to get \cmd{epsilon} and \cmd{phi} typeset as $\varepsilon$
+and $\varphi$ instead of $\epsilon$ and $\phi$, you can add option
+\verb+CharacterVariant={3,6}+ to the \cmd{setmathfont} call:
+\begin{verbatim}
+\setmathfont{Erewhon Math}[CharacterVariant={3,6}]
+\end{verbatim}
+
+This works for all shapes and weights of these characters:
+\verb+$\symit{\epsilon}$+,\\
+\verb+$\symup{\epsilon}$+, \verb+$\symbf{\epsilon}$+,
+\verb+$\symbfit{\epsilon}$+ are output as
+\setmathfont{Erewhon Math}[CharacterVariant={3,6}]
+$\symit{\epsilon}$, $\symup{\epsilon}$, $\symbf{\epsilon}$, $\symbfit{\epsilon}$
+instead of
+\setmathfont{Erewhon Math}
+$\symit{\epsilon}, \symup{\epsilon}, \symbf{\epsilon}, \symbfit{\epsilon}$.
+
+The same is true for \verb+\phi+ of course. Please note that curly braces are
+mandatory whenever more than one ``Character Variant’’ is selected.
+
+\begin{table}[ht]
+ \centering
+ \caption{Character variants.}
+ \label{cv}
+ \begin{tabular}{@{}>{\ttfamily}lccl@{}}
+ \hline
+ & Default & Variant & Name\\
+ \hline
+ cv00 & $0$ & $\mupvarzero$ & 0 \\
+ cv01 & $\hslash$ & $\hbar$ & \cmd{hslash} \\
+ cv02 & $\emptyset$ & $\varemptyset$ & \cmd{emptyset} \\
+ cv03 & $\mitepsilon$ & $\mitvarepsilon$ & \cmd{epsilon} \\
+ cv04 & $\mitkappa$ & $\mitvarkappa$ & \cmd{kappa} \\
+ cv05 & $\mitpi$ & $\mitvarpi$ & \cmd{pi} \\
+ cv06 & $\mitphi$ & $\mitvarphi$ & \cmd{phi} \\
+ cv07 & $\mitrho$ & $\mitvarrho$ & \cmd{rho} \\
+ cv08 & $\mitsigma$ & $\mitvarsigma$ & \cmd{sigma} \\
+ cv09 & $\mittheta$ & $\mitvartheta$ & \cmd{theta} \\
+ cv10 & $\mitTheta$ & $\mitvarTheta$ & \cmd{Theta} \\
+ \hline
+ \end{tabular}
+\end{table}
+
+\subsection{Stylistic sets}
+\label{ssection-ss}
+
+\FOTF{} provides four ``Stylistic Sets’’ options to choose between different
+glyphs for families of mathematical symbols.
+
+\verb+StylisticSet=4+, alias%
+\footnote{These \texttt{Style} aliases are provided by \file{fourier-otf.sty}.}
+\verb+Style=leqslant+, converts (large) inequalites into their slanted
+variants as shown by table~\vref{ss04}.
+\begin{table}[ht]
+ \centering
+ \caption{Stylistic Set 4 -- \texttt{leqslant} (slanted inequalities)}
+ \label{ss04}
+ \begin{tabular}{@{}lcc@{}}
+ \hline
+ Command & Default & Variant \\
+ \hline
+ \cmd{leq} & $\leq$ & $\leqslant$ \\
+ \cmd{geq} & $\geq$ & $\geqslant$ \\
+ \cmd{nleq} & $\nleq$ & $\nleqslant$ \\
+ \cmd{ngeq} & $\ngeq$ & $\ngeqslant$ \\
+ \cmd{leqq} & $\leqq$ & $\leqqslant$ \\
+ \cmd{geqq} & $\geqq$ & $\geqqslant$ \\
+ \cmd{eqless} & $\eqless$ & $\eqslantless$ \\
+ \cmd{eqgtr} & $\eqgtr$ & $\eqslantgtr$ \\
+ \cmd{lesseqgtr} & $\lesseqgtr$ & $\lesseqslantgtr$ \\
+ \cmd{gtreqless} & $\gtreqless$ & $\gtreqslantless$ \\
+ \cmd{lesseqqgtr} & $\lesseqqgtr$ & $\lesseqqslantgtr$ \\
+ \cmd{gtreqqless} & $\gtreqqless$ & $\gtreqqslantless$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+\verb+StylisticSet=5+, alias \verb+Style=smaller+, converts some symbols into
+their smaller variants as shown by table~\vref{ss05}.
+\begin{table}[ht]
+ \centering
+ \caption{Stylistic Set 5 -- \texttt{smaller} (smaller variants)}
+ \label{ss05}
+ \begin{tabular}{@{}lcc@{}}
+ \hline
+ Command & Default & Variant \\
+ \hline
+ \cmd{in} & $\in$ & $\smallin$ \\
+ \cmd{ni} & $\ni$ & $\smallni$ \\
+ \cmd{mid} & $\mid$ & $\shortmid$ \\
+ \cmd{nmid} & $\nmid$ & $\nshortmid$ \\
+ \cmd{parallel} & $\parallel$ & $\shortparallel$ \\
+ \cmd{nparallel} & $\nparallel$ & $\nshortparallel$ \\
+ \cmd{parallelslant} & $\parallel$ & $\shortparallelslant$ \\
+ \cmd{nparallelslant} & $\nparallelslant$ & $\nshortparallelslant$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+\verb+StylisticSet=6+, alias \verb+Style=subsetneq+, converts some inclusion
+symbols as shown by table~\vref{ss06}.
+\begin{table}[ht]
+ \centering
+ \caption{Stylistic Set 6 -- \texttt{subsetneq} (inclusion variants)}
+ \label{ss06}
+ \begin{tabular}{@{}lcc@{}}
+ \hline
+ Command & Default & Variant \\
+ \hline
+ \cmd{subsetneq} & $\subsetneq$ & $\varsubsetneq$ \\
+ \cmd{supsetneq} & $\supsetneq$ & $\varsupsetneq$ \\
+ \cmd{subsetneqq} & $\subsetneqq$ & $\varsubsetneqq$ \\
+ \cmd{supsetneqq} & $\supsetneqq$ & $\varsupsetneqq$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+\verb+StylisticSet=7+, alias \verb+Style=parallelslant+, converts
+``parallel’’ symbols into their slanted variants as shown by table~\vref{ss07}.
+\begin{table}[ht]
+ \centering
+ \caption{Stylistic Set 7 -- \texttt{parallelslant} (slanted variants)}
+ \label{ss07}
+ \begin{tabular}{@{}lcc@{}}
+ \hline
+ Command & Default & Variant \\
+ \hline
+ \cmd{parallel} & $\parallel$ & $\parallelslant$ \\

+ \cmd{nshortparallel} & $\nshortparallel$ & $\nshortparallelslant$ \\
+ \hline
+ \end{tabular}
+\end{table}
+
+To enable Stylistic Sets 4, 6 and 7 for \FOTF{}, you should enter
+\begin{verbatim}
+\setmathfont{Erewhon Math}[StylisticSet={4,6,7}] or
+\usepackage[Style={leqslant,subsetneq,parallelslant}]{fourier-otf}
+\end{verbatim}
+then, \verb+\[x\leq y \quad A \subsetneq B\quad D \parallel D' \]+
+will print as
+\setmathfont{Erewhon Math}[StylisticSet={4,6,7}]
+\[x\leq y \quad A \subsetneq B\quad D \parallel D' \]
+instead of
+\setmathfont{Erewhon Math}
+\[x\leq y \quad A \subsetneq B\quad D \parallel D' \]
+
+\clearpage

+\end{itemize}
+
+\subsection{Mathematical alphabets}
+\label{ssec-math-alphabets}
+
+\begin{itemize}
+\item All Latin and Greek characters are available in italic, upright, bold
+ and bold italic via the \verb+\symit{}+, \verb+\symup{}+, \verb+\symbf{}+
+ and \verb+\symbfit{}+ commands.
+
+\item Calligraphic alphabet (\cmd{symscr} or \cmd{symcal} or
+ \cmd{mathcal} command), uppercase only:
+
+ $\symscr{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
+
+\item Blackboard-bold alphabet (\cmd{symbb} or \cmd{mathbb} command),
+ uppercase, lowercase and digits:
+
+ $\symbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
+
+ $\symbb{abcdefghijklmnopqrstuvwxyz\quad 0123456789}$
+
+\item Fraktur alphabet is borrowed from Latin Modern,
+
+ $\symfrak{ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz}$
+
+ but this can overwritten, i.e.
+\begin{verbatim}
+\setmathfont{STIX2Math.otf}[range=frak,Scale=MatchUppercase]
+$\symfrak{ABCDEFGHIJKL...XYZ abcdefghijkl...xyz}$
+\end{verbatim}
+\setmathfont{STIX2Math.otf}[range=frak,Scale=MatchUppercase]

+$\symsfup{ABCDEFGHIJKLM abcdefghijk}\quad\symsfit{NOPQRSTUVWXYZ mnopqrstuvwxyz}$
+
+ but it can be borrowed from another Math font, i.e.
+\begin{verbatim}
+\setmathfont{STIX2Math.otf}[range={sfup,sfit},
+ Scale=MatchUppercase]
+$\symsfup{ABCD...klm}\quad\symsfit{NOPQ...xyz}$

+$\symtt{ABCDE...XYZ abcde...xyz}$
+\end{verbatim}
+\setmathfont{STIX2Math.otf}[range=tt,Scale=MatchUppercase]
+$\symtt{ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz}$
+\end{itemize}
+
+\subsection{Fourier ornaments}
+
+All logos and ornaments provided by \FGUT{} (\pkg{fourier-orns.sty}) are
+available with \FOTF{} when loaded by \verb+\usepackage{fourier-otf}+.
+
+\pkg{fourier-orns.sty} as of v2.0 automatically fetches its glyphs in
+a specific OpenType font with LuaTeX or XeTeX engines and from
+a Type\,1 font otherwise (pdfTeX).
+
+\begin{raggedright}
+\begin{itemize}
+
+\item \showtchar{textpertenthousand}, \textit{\textpertenthousand},

+ \showtchar{oldpilcrowfive} aaaa, %\\
+ \showtchar{oldpilcrowsix} aaaaaaaaaaa.
+\end{itemize}
+\end{raggedright}
+
+Finally, some symbols are also provided in math mode, with other names:

+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
+* 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, TeXGyrePagella and DejaVu.
+* 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. This license is available with a FAQ at:

+\maketitle
+
+This document uses the file \texttt{unicode-math-table.tex}
+to print every symbol defined by the \textsf{unicode-math}
+package.
+Use this document to find the command name or the Unicode glyph slot for a symbol that you wish to use.
+The following fonts are shown: (with approximate symbol counts)
+\begin{itemize}
+\item[\Llm] \mathversion{lm} $\mathup{Latin\ Modern\ Math}$ (\ref{count:lm})
+%\item[\Lxits] \mathversion{xits} $\mathup{XITS\ Math}$ (\ref{count:xits})
+\item[\Lstix] \mathversion{stix} $\mathup{STIX\ Math\ Two}$ (\ref{count:stix})
+\item[F] \mathversion{erewhon} $\mathup{Erewhon\ Math}$ (\ref{count:erewhon})
+\item[\Lpagella] \mathversion{pagella} $\mathup{TeX\ Gyre\ Pagella\ Math}$ (\ref{count:pagella})
+\item[\Ldejavu] \mathversion{dejavu} $\mathup{DejaVu\ Math\ TeX\ Gyre}$ (\ref{count:dejavu})
+%\item[\Lfira] \mathversion{fira} $\mathup{Fira\ Math}$ (\ref{count:fira})
+\end{itemize}
+Symbols defined in Plain \TeX\ are indicated with {\color[gray]{0.6} \textsuperscript{\sffamily (p)}} after their macro name.
+\LaTeX\ follows Plain \TeX, but defines a handful more, indicated with {\color[gray]{0.6} \textsuperscript{\sffamily (l)}}.
+Symbols defined in \textsf{amssymb} are indicated with {\color[gray]{0.6} \textsuperscript{\sffamily (a)}}.
+
+Note that this list of fonts is not intended to be exhaustive but I am happy to add new fonts by request if they are distributed in \TeX\ Live.\footnote{Only a single \TeX\ Gyre Math font is shown here by design as they all largely have the same symbol coverage.}
