+\section{Introduction}
+The NewComputerModern FontFamily is a huge extension (``huge'' in terms of
+the number of additional glyphs)
+of the \verb|lm| fonts. It is not just a family adding random missing glyphs but it
+adds support for several more languages and shapes needed for academic (and not only) work.
+Currently it supports among others, Greek\footnote{from Claudio Beccari's Greek.},
+Cyrillic\footnote{from the \texttt{cmu} package.}, Hebrew, Cherokee and
+Coptic. Since it supports
+diacritics stacking the number of languages that use the Latin alphabet is greatly expanded. 
+Diacritics stacking is also needed for Greek for papyrological work and this is also supported.
+
+Version 4.0 adds to the classic design of computer modern new shapes for Latin and Greek,
+in particular it adds families for Medieval Latin and Uncial Greek matching in style to the
+main family.
+
+In terms of weights and sizes, all of its shapes come in Regular, Book weights
+at 10 and 8 point sizes and in Bold at 10 points.
+
+Mathematics is also supported in Regular and Book weights, currently providing
+a full coverage of the Unicode Math blocks (with a few more glyphs needed for Mathematics
+that Unicode has forgotten to encode).
+
+\textit{What follows is a sequence of commands and results so as to show how to access all features
+of the fonts. Character tables are also included}.
+
+\section{How to load the fonts}
+The simpler way to load the fonts is through the \verb|fontsetup| package. The command
+
+\verb|\usepackage[default]{fontsetup}|
+
+\noindent will load the Book weight of the NewCM family, and
+
+\verb|\usepackage[olddefault]{fontsetup}|
+
+\noindent will load the Regular weight.
+
+Also notice that the fonts support the microtype package for fine typographic tuning. See the
+documentation of microtype for this.
+
+\section{The Latin alphabet}
+
+\subsection{Ligatures and stylistic alternatives in Latin}
+{\newcmaltk
+The Serif font includes additional
+ligatures fb ffb ffh ffj ffk fft fh fj ft fk and the same with longs instead of f
+in the \textit{default} liga table (in addition to the default fi fl ffi ffl ff).
+It also includes an alternative k (in the cv01 table) and
+{\newcmdlig sp ch ck ct st}
+in the dlig table. Finally it also inludes} ``end'' {\newcmaltk versions for the letters
+a, e, m, n and r in the cv02 table.
+}
+To access the alternative k load the relative font (here the Book weight) with
+
+\verb|\setmainfont[CharacterVariant=1]{NewCM10-Book.otf}|
+
+To load the same font with the dlig table enabled use
+
+\verb|\setmainfont[RawFeature=+dlig]{NewCM10-Book.otf}|
+
+and to load the font with endings variations use
+
+\verb|\setmainfont[CharacterVariant=2]{NewCM10-Regular.otf}|
+
+Of course the above can be mixed separating the optional arguments with comma,
+or one can define a custom font say by using
+
+\verb|\newfontfamily\myfont[<options to enable>]{NewCM10-Regular.otf}|
+
+\begin{center}
+  \begin{tabular}{c|c|c|c}
+    Regular &   k & a e m n r & sp ch ck ct st\\ \hline
+    cv01 & {\newcmaltk k} & & \\ \hline
+    cv02 & & {\newcmaltendings a e m n r} &  \\ \hline
+    dlig & & & {\newcmdlig sp ch ck ct st}
+  \end{tabular}
+\end{center}
+
+\subsection{Old Italic}
+
+The fonts also fully support the Old Italic Unicode block
+(U10300--U1032F) in the Sans font. For example, the slots
+U10307, U10310, U10312, U10314, U1031F and U1032F are
+{\sffamily\char"10307\char"10310\char"10312\char"10314\char"1031F\char"1032F}.
+
+\subsection{Diacritics Stacking}
+\marginpar{\begin{center}
+{\color{red}$\rightarrow$}\ \xstacked\ {\color{red}$\leftarrow$}
+\end{center}}
+Diacritics stacking is supported at least for Regular, Book and Bold upright seriffed fonts.
+In the margin you can see an example of stacking on the letter ``x''. If you need to enter
+these accents you can use the \verb|\char| command or just copy-paste from the following line
+(from this pdf file or the provided source \TeX\ file):
+\begin{center}
+  \textit{Some} of the upper accents\\[1ex]
+{\Large  ̀\quad ́\quad ̂\quad ̃\quad ̄\quad ̅\quad\quad ̆\quad ̇\quad ̈\quad ̉\quad ̊\quad ̋}\\
+{\Large  ̌\quad ̍\quad ̎\quad ̏\quad ̑\quad ̓\quad ̔\quad ̽\quad ̾\quad ̚\quad ͆\quad ͝\quad ͠\quad ͡}\\
+\textit{Some} of the lower accents\\
+{\Large ̧\quad ̖\quad ̗\quad ̘\quad ̙\quad ̜\quad ̝\quad ̞\quad ̟\quad ̠\quad ̣\quad ̤\quad ̥\quad ̦}\\
+{\Large ̩\quad ̪\quad ̫\quad ̬\quad ̭\quad ̮\quad ̯\quad ̰\quad ̱\quad ̲\quad ̹\quad ̺\quad ̻\quad ̼\quad ͇\quad ͈\quad ͉\quad ͍}
+  \end{center}
+Please note that stacking is better supported with xetex. With luatex your milage will vary
+since the support in the lua engine does not look complete.
+
+Also notice that your text editor may not support stacking. The editor may show the
+accents one after the other, but the pdf produced by xetex will have the accents stacked.
+
+
+\section{Greek}
+
+
+The full Unicode Greek block is supported, which is
+\begin{itemize}
+  \item U0370--U03FF for monotonic, where missing glyphs, such as Heta (Ͱ),
+    Pamphilian digamma (ͷ) etc, have been added. For example, it is now possible to write
+
+    \centerline{βιϐλίο instead of βιβλίο.}
+    
+  \item U1F00--U1FFF for polytonic, and
+  \item U10140--U1018F for ancient Greek numbers.
+\end{itemize}
+    
+
+\begin{theorem}[Πυθαγόρειον]
+Ἐν τοῖς ὀρθογω\-νί\-οις τριγώνοις τὸ ἀπὸ τῆς τὴν ὀρθὴν γωνίαν ὑπο\-τει\-νού\-σης πλευρᾶς
+τετράγωνον ἴσον ἐστὶ τοῖς ἀπὸ τῶν τὴν ὀρθὴν\hspace{-1pt} γωνίαν περιεχουσῶν πλευρῶν τετραγώνοις.
+\end{theorem}
+
+
+Small Caps is included (in Mono font too) and all polytonic accents of Greek.
+Ypogegrammeni is the default for all characters including Small Caps and prosgegrammeni
+is offered as an alternative shape in the \texttt{ss01} lookup table:
+\begin{center}
+\begin{tabular}{c|c|c}
+ &  ypogegrammeni & prosgegrammeni\\ \hline
+regular &  ᾋ ᾟ ᾯ \textsc{ᾳῃῳ} & {\textprosgegrammeni{ᾋ ᾟ ᾯ \textsc{ᾳῃῳ}}}\\ \hline
+sans &{\sffamily  ᾋ ᾟ ᾯ \textsc{ᾳῃῳ}} & {\sffamily{\textprosgegrammeni{ᾋ ᾟ ᾯ \textsc{ᾳῃῳ}}}}\\ \hline
+mono & {\ttfamily  ᾋ ᾟ ᾯ \textsc{ᾳῃῳ}} & {\ttfamily{\textprosgegrammeni{ᾋ ᾟ ᾯ \textsc{ᾳῃῳ}}}}
+\end{tabular}
+\end{center}
+The prosgegrammeni alternates can be accessed with 
+
+\medskip
+
+\verb|\textprosgegrammeni{<text>}|
+
+\noindent or the
+
+\verb|{\prosgegrammeni <text>}|
+
+\medskip
+
+\noindent of the \texttt{fontsetup} package.
+
+\subsection{Other character variants}
+
+Guillemots (left and right) have a different shape for Greek. For this to work
+the fonts must be loaded with the cv04 character variant.
+
+  
+Compare the default guillemots: «» with Greek guillemots:
+\textlang{greek}{\newcmgreekguillemots «»}. 
+
+There is a serious problem with Unicode and the Greek anoteleia (U0387); the Greek semicolon. 
+Unicode ``thinks'' that this character is the same with periodcentered (U00B7). This influences
+the way keyboards are configured by several vendors such as xorg. Anoteleia
+is a dot written at x-height and not at 1/2 the x-height as the periodcentered.
+Although Unicode recognizes the problem\footnote{personal communication}, althought
+they recognize that with their current standard you can not correctly write the Greek language,
+they refuse to fix it, justifying it by saying the magical words ``backwards compatibility''
+(to a \ldots{}mistake, one could add).
+
+NewComputerModern can not allow this, as it defies the purpose of its
+existence, which is to properly write every supported language. So
+enabling the CharacterVariant 04 (cv04) in addition to correct
+guillemots for Greek it maps periodcentered (produced by the keyboards
+(in Greek Linux keyboards by AltGr+q) to proper anoteleia.
+
+It also fixes a long standing issue with the Greek apostrophe (᾽)(U1FBD) which
+is not the same with quoteright (’)(U2019). U1FBD named as ``Greek Koronis''
+by Unicode is the proper character. This creates another problem that has to do with
+quotes inside quotes. The internal quotes in Greek should be written with
+the characters quotedblleft (\char"201C) and quotedblbase (\char"201E)
+(see~\cite{2}). For example, this is correct for Greek
+\begin{center}
+ {\newcmgreekguillemots  «άλφα \quoteleft βήτα\quoteright»}
+\end{center}
+But the keyboards only produce quotesingle which is already mapped to apostrophe.
+So when enabling cv04 one can define the commands
+
+\verb|\newcommand\quoteleft{\char"201C}|
+
+\noindent and
+
+\verb|\newcommand\quoteright{\char"201E}|
+
+\noindent for the rare case one needs quotes inside quotes. The \verb|fontsetup| package
+does this automatically for Greek if the \verb|xgreek| package has been loaded \textit{before}
+the \verb|fontsetup| package. Otherwise, for non-Greek documents with small passages of Greek,
+the author may enable \verb|cv04| by creating a custom command such as
+
+\noindent\verb|\newfontfamily\propergreek[CharacterVariant=4]{NewCM10-Book.otf}|
+
+
+A phrase with Greek quotes inside quotes, proper anoteleia, and proper apostrophe is
+
+\begin{center}
+{\newcmgreekguillemots  «φώναζε: \quoteleft απ' έξω την προπαίδεια\quoteright»· σαν εκδίκηση ακουγόταν\ldots}
+\end{center}
+
+
+\subsection{Archaic Greek writing}
+The Sans Serif Regular font provides access to 6th century bce and 4th century bce Greek capitals
+in ss04 and ss03 lookups. The \texttt{fontsetup} package provides commands such as\begin{center}
+\verb|\textivbce{}|, \verb|\ivbce|, \verb|\textvibce{}| and \verb|\vibce|
+\end{center}
+%to access them if loaded
+%with the \verb|[default]| or \verb|[olddefault]| option.
+\begin{center}
+  \begin{tabular}{c}
+    6th century bce:\\ \hline
+    \textvibce{ΜΗΔΕΙΣ ΑΓΕΩΜΕΤΡΗΤΟΣ ΕΙΣΙΤΩ}\\ \hline\hline
+    4th century bce:\\ \hline
+     \textivbce{ΜΗΔΕΙΣ ΑΓΕΩΜΕΤΡΗΤΟΣ ΕΙΣΙΤΩ}
+  \end{tabular}
+\end{center}
+Moreover, all fonts (except Mono \&\ Math) support Ancient Greek
+Numerals (the full Unicode block of Greek digits U10140--U1018E is supported),
+with most symbols designed from scratch (and did not exist in C. Beccari's original fonts).
+A few of the new symbols:
+\begin{center}
+𐅋𐅌𐅍𐅏𐅯𐅴𐆉
+\end{center}
+The four numerals that already existed in 
+this range (that is U10144--U10147) in Beccari's fonts have been altered to a new
+design matching the style of cm but also provide some Ancient Greek flair.
+The new designs in Serifed and SansSerifed are:
+\begin{center}
+𐅄𐅅𐅆𐅇 \quad \textsf{𐅄𐅅𐅆𐅇}
+\end{center}
+The \texttt{fontsetup} package provides commands for all of the above symbols.
+The commands follow the Unicode name of each slot (minus the ``Greek Acrophonic'').
+So the Unicode slot U1014F named ``Greek Acrophonic Attic Five Staters'' can be accessed
+with the command \verb|\atticfivestaters| and it gives \atticfivestaters; and the
+slot u10182 named ``Greek Kyathos Base Sign'' can be accessed with the command
+\verb|\greekkyathosbasesign| and it gives \greekkyathosbasesign.
+
+\subsection{Support for Papyrology}
+Papyrology needs to declare that a glyph is missing from the papyrus or
+the papyrus is worn at this point and the papyrologist adds the missing glyph
+but it is not clear from the papyrus. This is done by adding a dot below the glyph
+and it is supported for all Greek glyphs in the upright fonts monotonic or polytonic:
+\begin{center}
+{\Large Α̣\quad Ἆ̣\quad ᾞ̣\quad ἇ̣\quad ᾦ̣\quad ῥ̣}
+\end{center}
+where in the source we just typed the dot below (char U0323) after the glyph.
+This feature is supported for the 4th bce and 6th bce Greek in Sans:
+\begin{center}
+  \textvibce{\Large Γ̣Ε̣Ω̣Μ̣Ε̣Τ̣Ρ̣Ι̣Α̣}
+  \quad\quad\textivbce{\Large Γ̣Ε̣Ω̣Μ̣Ε̣Τ̣Ρ̣Ι̣Α̣}
+\end{center}
+
+
+\subsection{Support for Chemistry}
+It happens often that Greek upright characters are needed in Chemistry. People often
+have trouble with this (and this is why packages such as \texttt{chemgreek} exist).
+If Greek keyboard is available then it is easy; you just type in Greek, say
+\texttt{β-glucan} to get ``β-glucan''.
+But many writers do not have the Greek keyboard enabled, and they do not need to.
+Usually they type \verb|$\beta$-glucan| but the result ``$\beta$-glucan'' is not satisfying.
+One can use the ``up'' versions typing \verb|$\upbeta$-glucan| but still the result
+``$\upbeta$-glucan'' looks more Math than Chemistry.
+To help with this, the \texttt{fontsetup} package provides commands such as \verb|\chemAlpha|,
+\verb|\chemalpha|, \verb|\chemBeta|, \verb|\chembeta|, etc. So this information essentially would
+only belong to the \verb|fontsetup| documentation if it was not for kappa and rho. If we type
+in Greek \texttt{κ-compound} we get ``κ-compound'' which is not satisfying, as kappa is too
+cursive for this use. So the NewCM family provides an alternative kappa for this reason
+and this is how \verb|\chemkappa| is defined in \verb|fontsetup|:
+
+\verb|\newcommand{\chemkappa}{\textrm{\char"03F0}}|:
+\begin{center}
+  We write \verb|\chemkappa-compound| and now get ``\chemkappa-compound''.
+\end{center}
+(The \verb|\textrm| command in the above definition is there to make the command work
+in math mode too.)
+Similar is the situation for \verb|\chemrho| (\chemrho) and \verb|\chemrhoalt| (\chemrhoalt).
+
+
+

+\section{Russian}
+Russian is supported using the glyphs from the \verb|cmu| package but it has considerable
+improvements (for example, the quality of the bold sans (see below)).
+\begin{verse}
+Я помню чудное мгновенье:\\
+Передо мной явилась ты,\\
+Как мимолетное виденье,\\
+Как гений чистой красоты.\\
+\hspace{3cm}(Пушкинъ)
+\end{verse}
+Again, as in Greek there is a different kind of guillemots for Russian which are available
+in CharacterVariant 3 (cv03). Compare:
+\begin{center}
+Defaults guillemots: «» \quad Russian guillemots: {\newcmrussianguillemots «»}\quad Greek guillemots: {\newcmgreekguillemots «»}
+\end{center}
+Same is the situation with Russian emdash which is shorter than the default:
+\begin{center}
+\begin{tabular}{rl}
+  Default emdash: & ---\\
+  Russian emdash: & {\newcmrussianguillemots ---}
+\end{tabular}
+\end{center}
+
+
+\section{Hebrew}
+\noindent The Hebrew blocks U0590--U05FF and Hebrew Presentation forms
+UFB1D--UFB4F are fully covered. and  A few letters from Hebrew: 
+\begin{center}
+ אבגדהושׁשּׂלּצּ
+\end{center}
+
+\section{Coptic and Epact Numbers}
+\noindent The Coptic language is fully supported. This covers the Coptic blocks
+in the Greek and Coptic Unicode
+block (U03E2--U03EF), the full Coptic Unicode block (U2C80--U2CFF) and the Coptic Epact Numbers
+(U102E0--U102FF).
+A few letters from Coptic and Epact numbers follow: 
+\begin{center}
+ⲗⲟⲅⲟⲥ ⲛ̀ⲁⲓⲅⲩⲡⲧⲓⲟⲥ \quad 𐋡 𐋢 𐋣 𐋤 𐋥
+\end{center}
+
+
+
+
+\section{Cherokee}
+Both Unicode blocks 
+U13A0--13FF and UAB70--UABBF for Cherokee are supported. A few letters are:
+\begin{center}
+  ᎣᎤᎹᏊᏐ  ꭳꭴꭷꮂꮔꮿ
+\end{center}
+
+
+\section{Medieval Latin and Uncial Greek}
+The family includes new shapes for medieval and uncial Greek.
+The \verb|fontsetup| package provides \verb|\textuncial{<text>}| and
+\verb|{\uncial text}| to use this shape. Let us write a sentence
+in this shape:
+\begin{center}
+  \begin{minipage}{9cm}
+{\uncial    The Pythagorean Theorem is one of the most important theorems in Mathematics.}\\
+{\uncial    Το Πυθαγόρειο Θεώρημα είναι από τα σημαντικότερα θε\-ω\-ρή\-μα\-τα των Mαθηματικών.}
+  \end{minipage}
+\end{center}
+\section{Braille}
+Braille, both 6dot (uni2801--uni283F)
+as well as 8dit (uni2840--uni28FF) patterns
+are included in two versions. The Regular font provides the
+characters for sighted persons (such as teachers) so they can easily see which dots are
+on and which off. The Sans font contains the true Braille characters. I decided to have the
+sighted version in the Regular font since a blind person does not need the real Braille pattern,
+as those are produced by embossers. The Braille patterns here are meant as fonts to
+typeset text mainly for sighted persons.
+\begin{center}
+  \begin{tabular}{c|c|c}
+    & 6dot & 8dot\\ \hline
+    Regular version & ⠅⠆⠇⠝⠞ & ⡂⡃⡄⡚⡛\\ \hline
+    Sans version &{\sffamily ⠅⠆⠇⠝⠞} &{\sffamily ⡂⡃⡄⡚⡛}
+  \end{tabular}
+\end{center}
+
+\section{Ipa symbols}
+
+\acro{IPA} symbols are included and following a suggestion of Huanyu Liu
+the kerning found in \texttt{tipa} package has been added here and further improved. Moreover
+the letters eth, eng, beta, theta and chi
+exists in \acro{IPA}-style in the fonts and are accessible in the ss05 lookup table since
+they are in a different design from the Latin and Greek letters.
+You can access this lookup table using the \verb|\textipa| and
+\verb|\textsansipa| commands of the fontsetup
+package.
+\begin{center}
+  \begin{tabular}{c|c|c}
+   & Non-\acro{IPA} & \acro{IPA}\\ \hline
+ Regular &   ð ŋ β θ χ & \textipa{ð ŋ β θ χ}\\ \hline
+ Sans & \textsf{ð ŋ β θ χ} & \textsansipa{ð ŋ β θ χ}
+  \end{tabular}
+\end{center}
+
+
+
+
+
+\section{Bold Sans}
+\texttt{lm} fonts and \texttt{cmu} fonts do not contain a properly made
+BoldSans. Their BoldSans is a stroke-extensi\-on of the Sans with rounded corners.
+NewCM fixes that and provides a true BoldSans:
+
+\hspace*{-5ex}\begin{tabular}{c|c}
+  LM & NewCM\\ \hline
+  & \\
+  \scalebox{6.8}{\lmboldsans XΞ}&\scalebox{6.8}{\textsf{\bfseries XΞЯДЛ}}
+\end{tabular}
+
+
+
+
+\section{Unicode Math coverage and options}
+NewCM provides
+full Unicode math support, that is 
+ all Mathematics Unicode Slots
+ presented in \url{http://www.unicode.org/charts/}
+  in both Math weights, Regular and Book. These blocks are:
+\hspace*{-5em} \begin{description}
+\item[Mathematical Symbols]
+\ \\
+Arrows (uni2190--uni21FF)\\
+Supplemental Arrows-A (uni27F0--uni27FF)\\
+Supplemental Arrows-B (uni2900--uni297F)\\
+Supplemental Arrows-C (u1F800--u1F8FF)\\
+Additional Arrows (uni2B00--uni2BFF)\\
+Miscellaneous Symbols and Arrows (uni2B00--uni2BFF)
+\item[Mathematical Alphanumeric Symbols] 
+\ \\ (u1D400--u1D7FF)\\

+    \ \\
+   Additional Shapes (uni2B00--uni2BFF)\\
+   Box Drawing (uni2500--uni257F)\\
+   Block Elements (uni2580--uni259F)\\

+   \end{description}
+
+\begin{wrapfigure}[8]{o}{0.08\textwidth}\vspace*{-1\baselineskip}
+\ \\[2ex]
+  \scalebox{8}{\color{gray}$\char"2BDA$}
+\end{wrapfigure}
+  Unfortunately, the \texttt{unicode-math} package does not
+provide commands currently for the hundrends of extra glyphs that have been added
+in order to fully cover the above Unicode ranges. The user can 
+consult the Unicode charts at the above link and access the required 
+glyph with \verb|\char"#| where \#\ is the Unicode number of the
+slot the glyph belongs to. 
+
+For example, \verb|\char"2BDA| will give the Hygeia symbol
+(uni2BDA) the Rod of Asclepius as shown above (grayed and scaled $\times 8$). The glyph
+that appeared in TUGboat (see \cite{1}), being more realistic will be moved to
+a new font in the future with ornaments.
+
+\subsection{Optical sizes for more glyphs}
+So far the fonts provided optical sizes for 1st and 2nd order exponents for letters. This was
+not true though for binary operators and some symbols commonly used in mathematics.
+For example, the \verb|\perp| symbol ($\perp$) often appears in 2nd order exponents
+and then it appeared very thin. Some printers could even hardly print its thin lines.
+Now, such glyphs plus several binary operators, such as $+$, $-$, $\pm$, $\dotplus$ etc
+are now provided in optical sizes, so that expressions such as
+$$+^{+^+}\ \perp^{\perp^\perp}\ *^{*^*}\quad\frac{|P_{F^\perp}(K)|}{e^{(x+y)^*}}$$
+appear on screen and print properly on printers.
+Zoom or print and compare with \texttt{lat\-in\-modern-math} font:
+\begin{center}
+  \includegraphics{opticalmathlm-cropped.pdf}
+\end{center}
+
+
+
+
+\subsection{Upright and extensible integrals}
+The Math fonts (both Regular and Book weights) include upright integrals
+in the ss02 StylisticSet.
+Use with
+
+\medskip
+
+\noindent\verb|\setmathfont[StylisticSet=2]{NewCMMath-Book.otf}|
+
+\noindent or
+
+\noindent\verb|\setmathfont[StylisticSet=2]{NewCMMath-Regular.otf}|
+
+\medskip
+
+\noindent or use the \verb|upint| option of the \texttt{fontsetup} package with
+\begin{verbatim}
+\usepackage[upint,default]{fontsetup}
+\end{verbatim}
+for the Book weight, or
+\begin{verbatim}
+\usepackage[upint,olddefault]{fontsetup}
+\end{verbatim}
+for the regular weight.
+
+
+Moreover, extensible integrals are supported by the fonts but \textit{NOT} by the Unicode TeX
+engines.
+The following code is a trick so that extensible integrals can be
+constructed using Lua\LaTeX. The result is shown at the end
+of the article.
+What the  code below does, is that it defines the slot uni222B (integral) as
+a delimiter. And then this is extended as a delimiter with the mechanism that
+the font provides.
+
+\begin{tabular}{l|r}
+  \begin{minipage}[c]{6cm}
+\begin{verbatim}
+\documentclass{article}
+\usepackage[default]{fontsetup}
+\begin{document}
+$
+\Uleft\Udelimiter 0 0 "222B
+\begin{pmatrix}
+  1\\2\\3\\4\\5\\6\\7\\8\\9
+\end{pmatrix}
+\Uright.
+$
+\end{document}
+\end{verbatim}
+  \end{minipage}
+  &
+  \begin{minipage}[c]{4cm}
+\begin{center}
+    \includegraphics{integral.pdf}
+\end{center}
+\end{minipage}
+\end{tabular}
+
+\subsection{Additional and alternative characters in Math}
+The Math fonts provide the character \verb|\varnothing| ($\varnothing$), as
+an alternative to \verb|\emptyset| (a slashed zero),
+through Character Variant \verb|cv01|. The \verb|fontsetup| package provides the option 
+`\verb|varnothing|' to easily switch to the alternative character.
+
+It also provides two more symbols that correspond to the commands
+
+\medskip
+
+  \verb|\nrightrightarrows| ($\nrightrightarrows$)
+
+\noindent and
+
+\verb|\nleftleftarrows| ($\nleftleftarrows$)
+
+\medskip
+
+\noindent
+and supported by the \verb|default| and \verb|olddefault| options of the \verb|fontsetup| package.
+These symbols are not in the Unicode Standard and so they are added in the
+Private Area of the fonts.
