# Itemize bullets are squared when using sans serif Latin Modern

I noticed that if you use the Latin modern font, loading it with the appropriate package and you set the default family to sans-serif, the bullets of the itemize environment are squared rather than rounded.

Why this happens and how to avoid it? Here there is a MWE and two screenshots, the first on the left showing the squared bullets and the second on the right about the normal rounded bullets.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage{lmodern}
\renewcommand{\familydefault}{\sfdefault}

\begin{document}
\begin{itemize}
\item a
\item b
\end{itemize}
\end{document}


EDIT: Seems that the problems starts when you write the \renewcommand{\familydefault}{\sfdefault} line, because I've noticed that if you delete the this line and try to write the itemize environment putting it into a {\sffamily } environment, the bullets appear in rounded shape (see below). Any idea about why this happens?

{\sffamily
\begin{itemize}
\item a
\item b
\end{itemize}
}

• I can't reproduce that on my system. – leandriis Mar 23 '20 at 13:56
• @leandriis you don't get squares? I do (using TL19 frozen). It comes down to the \familydefault change. – daleif Mar 23 '20 at 13:58
• @leandriis try to comment the \usepackage{lmodern} line, you'll see the bullets change their shape – andreagoo8 Mar 23 '20 at 13:59

A workaround with enumitem:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage{lmodern}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{enumitem}
\setlist[itemize,1]{label=$\bullet$}

\begin{document}

\begin{itemize}
\item a
\item b
\end{itemize}

\end{document}


• Thanks for the solution, it works. Any idea about the second question? (I have edited my original question) – andreagoo8 Mar 23 '20 at 14:35
• I think thatchanging \familydefault has a wider extent that simply changing the family. In the article class, \labelitemi is defined as \textbullet`, and it is taken from the default font. – Bernard Mar 23 '20 at 15:19
• Ok thanks fort the answer :) – andreagoo8 Mar 23 '20 at 16:40
