# Turning off TeXnical enhancements

I want to create a table for comparing TeX's typography with that of (approximated) other document solutions. I'd like to turn off all TeXnical enhancements for a single column of text—no ligatures, no good kerning, etc. I'm trying to use fontspec to do this, since Computer Modern simply doesn't have the ligatures I'm also looking to show off (fj for example).

Since the solution doesn't particularly ride on being usable in a table (to my knowledge), any solution where such typography is turned off within a group would work. :-)

Here is my attempt at a solution:

\documentclass{article}
\usepackage{fontspec,booktabs,array}
\begin{document}
\begin{table}
\centering
{
\setmainfont{Hoefler Text} % Linux Libertine also has fj I believe,
% but I do not have it installed on my system
\begin{tabular}{ c >{\addfontfeature{Ligatures=NoCommon}}c }
\toprule
\TeX & \MicrosoftWord \\
\midrule
Table & T{}a{}b{}l{}e \\
SALT  & S{}A{}L{}T    \\
AVAST & A{}V{}A{}S{}T \\
\midrule
efficient firefly & e{}f{}f{}i{}c{}i{}e{}n{}t f{}i{}r{}e{}f{}l{}y \\
\bottomrule
\end{tabular}
}
\caption{A comparison of \TeX\ and other word processing solutions
(such as \MicrosoftWord) in regards to
kerning, ligatures, and small capitals}
\label{tab:compare}
\end{table}
\end{document}


which does successfully turn off ligatures, but I've no idea how to 'turn off' kerning other than what I'm doing right now, which is very much not in the spirit of TeX (one that I am actively trying to advertise).

Dangit, should have looked closer at the manual.

If the font is OpenType, you can turn kerning on and off as well with a simple Kerning=(on|off) switch:

\begin{table}
\centering
{
\setmainfont{Corbel}
\begin{tabular}{ c >{\addfontfeature{Ligatures=NoCommon,Kerning=Off}}c }
\toprule
\TeX & \MicrosoftWord \\
\midrule
Table & Table \\
SALT  & SALT    \\
AVAST & AVAST \\
\midrule
efficient firefly & efficient firefly \\
\bottomrule
\end{tabular}
}
\caption{A comparison of \TeX\ and other word processing solutions
(such as \MicrosoftWord) in regards to
kerning, ligatures, and small capitals}
\label{tab:compare}
\end{table}


The trick now is finding an OTF that looks nice with the rest of my document. Anyway, hope this helps anybody else who might be looking for such a thing!

• An off-topic hint on making your code more reader- and debug-friendly: Since you're (presumably) still loading the array package, you could issue the command \newcolumntype{Z}{>{\addfontfeature{Ligatures=NoCommon,Kerning=Off}}c} in the preamble and then type \begin{tabular}{cZ} later on. – Mico Sep 3 '13 at 0:53
• @Mico Tip taken and very much appreciated! Makes the actual tabular-spec a lot cleaner. – Sean Allred Sep 3 '13 at 19:40
