[Tex/LaTex] LaTeX Calligraphic Script Bold

boldfontsmath-mode

Does anyone know how to bold calligraphic \mathscr fonts in a math environment? I can get a fancy calligraphic font if I use \mathscr, but \boldsymbol does not work, nor does \mathbf. There is a hack which uses poor man's bold, but I was wondering if there is an alternate way to do this "cleanly". I've also seen \bm used for \mathcal font, but that's not what I'm looking for unfortunately.

I'm using calligraphic fonts with the following packages:

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{mathrsfs}

Best Answer

The RSFS fonts are not available in a bold version. You can however use the \pmb command from the amsbsy package, which simulates a bold weight by putting three copies of the respective character next to each other.

\documentclass{article}

\usepackage{mathrsfs}
\usepackage{amsbsy}

\begin{document}
$\mathscr{ABC}$\par
$\pmb{\mathscr{ABC}}$
\end{document}

Example

Another option is to use one of the calligraphic fonts provided by the mathdesign package, which resemble the RSFS fonts very closely and have bold weights.

\documentclass{article}

\usepackage{mathrsfs}
\DeclareMathAlphabet{\mathscrbf}{OMS}{mdugm}{b}{n}

\begin{document}
$\mathscr{ABC}$\par
$\mathscrbf{ABC}$
\end{document}
