\begin{document}
\maketitle
Cochineal is a fork of Crimson, a remarkable creation of Sebastian Kosch inspired by oldstyle font designers. The name Cochineal is intended to suggest that, while it is crimson, there may be bugs involved. More than 1500 glyphs were added to Crimson, allowing a more than modest chance that some poor spacing or kerning or accent placement might have been introduced. Such problems will occur in the less frequented parts of the fonts, and I would appreciate reports of problems you may discover. You are unlikely to trip over issues if you stay within the bounds of, say, the T$1$ encoding. I did correct problems in a number of glyphs from Crimson that FontForge uncovered and that could have led to poor rendition on some platforms, especially MAC OS. I also changed the emsize to {\tt 1000} (the standard for PostScript-flavored Opentype) from the Crimson value of {\tt 1024} and rescaled accordingly.
Cochineal provides {\tt Roman}, {\tt Bold}, {\tt Italic} and {\tt BoldItalic}. (Crimson provided semibold weights but with only limited coverage, which I did not wish to extend as this would have required the creation of about 2000 additional glyphs. Bob Tennent's {\tt Crimson} package does support semibold and the other styles, though without my glyph additions.)
\textsc{Package Features:}\\
In addition to the encodings {\tt OT1}, {\tt T1}, {\tt TS1}, {\tt LY1} in general use by Western European (and some Eastern European) scripts, the package also offers {\tt LGR} with full support for monotonic, polytonic and some ancient Greek, and {\tt T2A} and {\tt OT2} Cyrillic support. All allow a choice from four figure styles---{\tt TLF} (tabular lining figures, monospaced and uppercase), {\tt LF} (proportional lining figures, uppercase), {\tt TOsF} (tabular oldstyle figures, monospaced and lowercase) and {\tt OsF} (proportional oldstyle figures, lowercase). The encodings {\tt OT1}, {\tt T1}, {\tt TS1}, {\tt LY1} offer \textsc{Small Caps}, even \textsc{\textit{Italics Small Caps}}, and additional figure styles---superiors, inferiors and denominators. These features are available from either \verb|fontspec| or from [pdf]\LaTeX. In \LaTeX, you access these through the macros \verb|\textsu|, \verb|\textinf| and \verb|\textde|, or through their font-switching equivalents \verb|\sufigures|, \verb|\infigures| and \verb|\defigures|. For example:
\begin{itemize}
\item
\verb|M\textsu{lle} Dupont| and \verb|M{\sufigures lle} Dupont| both produce M\textsu{lle} Dupont.
\item \verb|{\infigures 12345}| and \verb|\textinf{12345}| render as \textinf{12345}, dipping noticeably below the baseline, while \verb|{\defigures 12345}| and \verb|\textde{12345}| render as \textde{12345}, aligned with the baseline.
\end{itemize}
As of version $1.062$ ($2020$), there is a new \verb|\textfrac| macro that works as in the following examples:
\begin{itemize}
\item
(two arguments) \verb|\textfrac{31}{32}| renders as \textfrac{31}{32};
\item
(three arguments) \verb|\textfrac[2]{63}{64}| renders as \textfrac[2]{63}{64}.
\end{itemize}
In addition, there is a \verb|\textcircled| macro that makes \verb|\textcircled{W}| render as \textcircled{W}. Numerals can also be circled: \verb|\textcircled{2}| renders as \textcircled{2}.
\newpage
\textsc{Package Options and Macros:}\\
The package defines two macros, \verb|\useosf| and \verb|\useproportional|, useable only in the preamble, which determine the default figure style in text. A typical invocation would be something like
\begin{verbatim}
\usepackage{cochineal} % default figure style is tabular, lining
% load sans and typewriter fonts
% load a math font---it will use tabular lining figures in math
\useosf % switch from lining figures to oldstyle figures
\useproportional % switch from tabular to proportional
\end{verbatim}
There is a simpler way to achieve essentially the same result, but with the advantage that the figure styles are not loaded until after the math package (if any) is loaded, so that math always uses the default tabular lining figures.
\begin{verbatim}
% If you use babel, load it here, before cochineal
\usepackage[p,osf]{cochineal} % default figure style is proportional, oldstyle
% load sans and typewriter fonts
% load a math font---it will use tabular lining figures in math
\end{verbatim}
No matter what the default figure style in text, the package provides switches and macros to use any available figure style.
\begin{itemize}
\item
\verb|\textlf{}| and \verb|{\lfstyle }| give proportional lining figures;
\verb|\texttlf{}| and \verb|{\tlfstyle }| give tabular lining figures;
\verb|\textosf{}| and \verb|{\osfstyle }| give proportional oldstyle figures;
\verb|\texttosf{}| and \verb|{\tosfstyle }| give tabular oldstyle figures;
\verb|\textfrac{3}{4}| uses superior and denominator figures to make the fraction \textfrac{3}{4}.
\end{itemize}
The options that can be passed to {\tt cochineal.sty} are the following:
\begin{itemize}
\item {\tt scale} or {\tt scaled}: a magnification factor---e.g., {\tt scaled=1.02} enlarges all text controlled by the package by {\tt2}\%;
\item
{\tt p}, or {\tt proportional}: make proportional figures the default rather than tabular;
{\tt lf}, or {\tt lining}: make lining figures the default (this is already the default);
{\tt osf}, or {\tt oldstyle}: make oldstyle figures the default rather than lining;
\item {\tt sups}: use superior figures to make footnote markers, rather than the \LaTeX's default markers;
\item {\tt swashQ}: use Cochineal's swash \Qswash\ instead of its tamer default version, \Qnoswash;
\item {\tt scosf}: always use oldstyle figures within a small caps block;
\item {\tt theoremfont}: for theorem statements in the {\tt plain} style, use a doctored version of italics that has upright figures, braces, brackets, parentheses, exclamation mark, colon and semicolon. It is implemented as the {\tt slanted} shape, and there are two options you can add to the call to the {\tt cochineal} package to modify the way it outputs figures.
The default (neither of the following options is set) is to use upright figures within theorem text, but in the same alignment (proportional or tabular) and the same style (lining or oldstyle) as in general text.
Option {\tt thmtabular} causes figures in theorem text to render in tabular alignment, while option {\tt thmlining} causes figure styles to render in lining rather than oldstyle. The two may be used in conjunction, forcing figures in theorem text to render as tabular lining figures.
\end{itemize}
\section*{Mathematical accompaniment}
The package contains fonts for use as math letters that are derived from Cochineal Roman and Greek glyphs and the {\tt newtxmath} family. Note that $v$ and $\nu$ (Greek {\tt nu}) are quite distinct. Here's a sample.
\begin{verbatim}
% preamble should include, in this order:
\usepackage[T1]{fontenc}
% load babel here
\usepackage[p,osf]{cochineal}
\usepackage[varqu,varl,var0]{inconsolata}
\usepackage[scale=.95,type1]{cabin}
\usepackage[cochineal,vvarbb]{newtxmath}
\usepackage[cal=boondoxo]{mathalfa}
\end{verbatim}
\def\Pr{\ensuremath{\mathbb{P}}}
\def\d{\mathrm{d}}
%\thispagestyle{empty}
The typeset math below follows the ISO recommendations that only variables
be set in italic. Note the use of upright shapes for $\d$, $\mathrm{e}$
and $\uppi$. (The first two are entered as \verb|\mathrm{d}| and
\verb|\mathrm{e}|, and in fonts derived from {\tt mtpro2} or {\tt newtxmath},
the latter is entered as \verb|\uppi|.)
\textbf{Simplest form of the \textit{Central Limit Theorem}:} \textit{Let
$X_1$, $X_2,\cdots$ be a sequence of iid random variables with mean~$0$
and variance $1$ on a probability space $(\Omega,\mathcal{F},\Pr)$. Then}
\[\Pr\left(\frac{X_1+\cdots+X_n}{\sqrt{n}}\le v\right)\to\mathfrak{N}(v)\coloneq
\int_{-\infty}^v \frac{\mathrm{e}^{-t^2/2}}{\sqrt{2\uppi}}\,
\mathrm{d}t\quad\mbox{as $n\to\infty$,}\]
\textit{or, equivalently, letting} $S_n\coloneq\sum_1^n X_k$,
\[\mathbb{E} f\left(S_n/\sqrt{n}\right)\to \int_{-\infty}^\infty f(t)
\frac{\mathrm{e}^{-t^2/2}}{\sqrt{2\uppi}}\,\mathrm{d}t
\quad\mbox{as $n\to\infty$, for every $f\in\mathrm{b}
\mathcal{C}(\mathbb{R})$.}\]

\section*{Cochineal's TS1 (textcomp)}
Coverage of TS1 has been enriched as of version $1.062$ so that it now qualifies as sub-encoding $0$, with essentially all TS1 features available.
\fonttable{Cochineal-Roman-ts1}
\newpage
\section*{Typesetting Greek with LaTeX}
Cochineal offers a rather complete LGR-encoded glyph collection, lacking just a few ancient symbols.
\fonttable{Cochineal-Roman-tlf-lgr}
Setting up your source file to use LGR usually involves {\tt babel} and {\tt substitutefont}. See the documentation of {\tt nimbus15} for details.
\newpage
\section*{Typesetting Russian}
With T$2$A encoding, the process is the same as with other T$2$A-encoded fonts, though the gaps in coverage may affect users of a number of non-Russian Cyrillic scripts. The only figure style provided is tabular lining (TLF.)
\fonttable{Cochineal-Roman-tlf-t2a}
\newpage
The OT$2$ encoding (supposedly obsolete, but still useful) is intended for limited use in producing Russian characters with a Western keyboard, making by means of \TeX\ a transliteration of ASCII for most characters in the range 33--122, and providing ligatures to generate the rest. See the documentation of {\tt nimbus15} for further details.
\fonttable{Cochineal-Roman-tlf-ot2}
\end{document}
\newpage
\section*{Additional glyphs for use in German orthography}
Prior to version {\tt1.050}, {\tt cochineal} offered basic support for German orthography, having all required accented glyphs and the lower case \ss, as well as a small caps \textsc{\ss}. Under LaTeX, the T$1$ encoding contained \verb|S_S|, but only as a synthesized character in the {\tt tfm}. Unicode users could not make use of \verb|S_S| as it was not present in the~{\tt otf}. So, with unicode tex processing:
\begin{verbatim}
{\addfontfeature{StylisticSet=1}\ss\ \textsc{\ss}}
\end{verbatim}
typesets, as in LaTeX processing, to
\ss\ \textsc{\ss}
Note also that in unicode processing, in order to obtain the expected case change behavior, it may be necessary to add in your preamble:
\begin{verbatim}
\uccode`ß="1E9E
\end{verbatim}
As of version {\tt1.050} of {\tt cochineal}, there are now glyphs in each style for {\tt U+1E9E} and for its small caps version, as well as \verb|S_S| as a real character, accessible under unicode TeX. The glyphs may be used as the uppercase and small caps versions of {\tt germandbls}. Currently, the new glyphs are not available in any of the LaTeX encodings and must be used via unicode TeX.
The following tables show how to access the new glyphs in unicode TeX. Note that you will need to set {\tt StylisticSet=1} if you wish not to use the new sharp-s glyphs.
