\subsetneq in bold font [duplicate]

Question

My tags are follows:

\documentclass{book}
\usepackage{amsmath,amssymb}

\begin{document}

$\boldsymbol{\subsetneq}$

\end{document}

I got the symbol in roman only but I need in bold face, any suggestions...

Answer 1

works with package bm

\documentclass{book}
\usepackage{amsmath,amssymb,bm}
\begin{document}

    $\bm{\subsetneq}$ $\subsetneq$

\end{document}

Using a proper mathfont also helps:

\documentclass{book}
\usepackage{amsmath,amssymb}
\usepackage{kpfonts}
\begin{document}

    $\boldsymbol{\subsetneq}$ $\subsetneq$

\end{document}

Answer 2

If you use unicode-math, there are three OpenType math fonts (as of 2019) that come in bold: Khaled Hosny’s free fonts XITS Math and Libertinus Math, and the commercial Minion Math.

The package will automatically load the bold weight as version=bold, but you can load any arbitrary OpenType or TrueType font with a command such as \setmathfont[version=bold]{XITS Math Bold}.

If you also load amsmath, \boldsymbol{\subsetneq} will still work. The unicode-math package by itself still supports the legacy commands {\boldmath ...} and {\mathversion{bold} ...}.

Answer 3

As alternative you could use or amsbsy package putting the command \pmb. See the image and MWE in attachment.

\documentclass{book}
\usepackage{amsmath,amssymb,amsbsy}
\begin{document}
$\pmb{\subsetneq}$
\end{document}
