# Package chemmacros changes \textbullet

The following document produces a weird shaped \textbullet:

\documentclass{article}
\def\sfdefault{hlcn}
\begin{document}
\sffamily\Huge
\textbullet
\end{document}


Commenting out the chemmacros package, or the \sfdefault change produce a regular rounded one:

and I thought this was the Lucida Casual font... What is going on?

• Try \usepackage[expert]{lucidabr}

This is part of what I get from the font table of hlcrn8c (the font used for font encoding TS1, family hlcn, series m and shape n):

The bullet corresponds to \char"88 (octal ´210). So it's a precise choice by Bigelow and Holmes.

I get the same with or without chemmacros (but as I don't have the obsolete lucidabr package, I used lucimatx).

You get a round bullet by undeclaring the association of \textbullet with TS1

\documentclass[noamssymb]{beamer}
\usepackage{lucimatx} % noamssymb is necessary with lucimatx
\renewcommand\sfdefault{hlcn}
\usepackage{chemmacros}
\UndeclareTextCommand\textbullet{TS1}
\DeclareTextCommandDefault\textbullet{$\bullet$}
\begin{document}
\begin{frame}
\Huge
\textbullet
\end{frame}
\end{document}


Without Lucida packages:

\documentclass{beamer}
\usepackage{chemmacros}

\renewcommand\sfdefault{hlcn}

\AtBeginDocument{%
\UndeclareTextCommand\textbullet{TS1}%
\DeclareTextCommandDefault\textbullet{$\bullet$}%
}

\begin{document}

\begin{frame}
\Huge
\textbullet
\end{frame}

\end{document}

• Actually, I get the same "problem" behaviour without any lucida package, just with \def\sfdefault{hlcn}. Could it be my font installation is old/broken? But still, loading chemmacrosmakes a difference Jan 3 '17 at 11:27
• @Jellby What chemmacros does is to enable TS1. When it is enabled, the bullet is taken from the TS1 font, so the one in the picture. Jan 3 '17 at 11:29
• And how would I enable the "curly" \textbullet without chemmacros? I can't just use \usepackage[TS1]{fontenc}... Jan 3 '17 at 18:38
• @Jellby \usepackage{textcomp} Jan 3 '17 at 18:55
