It is often recommended to include \usepackage[T1]{fontenc}, but I have been hit by the following difference:

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
texttt: \texttt{-->}

verb: \verb+-->+
\end{document}

Without fontenc both render the same -->. But with fontenc the first is rendered as ->.

Are there other such differences to expect?

In my opinion, it was an oversight when the EC fonts were developed.

You can disable the ligatures (in pdflatex) with microtype.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{microtype}

\DisableLigatures[-,?,!,<,>]{encoding=T1,family=tt*}


\begin{document}


texttt: \texttt{--> --->}


verb: \verb+--> --->+


\texttt{?! ff fi fl ffi ffl << >>}


\end{document}

Without the \DisableLigatures line you'd get

With XeLaTeX or LuaLaTeX there is no problem, because the monospaced font is loaded without TeX ligatures enabled.

\documentclass{article}
\usepackage{fontspec}

\begin{document}


texttt: \texttt{--> --->}


verb: \verb+--> --->+


\texttt{?! ff fi fl ffi ffl << >>}


\end{document}

  • Thank you! Does it make a difference where I add the line \usepackage[scaled]{beramono} so before or after? (I cannot see any, but then...) – false Sep 16 '23 at 07:31
  • @false beramono has no “hyphen ligatures”, as far as I can see. Depending on your needs, you may want to disable the “guillements ligatures”, though. – egreg Sep 16 '23 at 08:49
