First a MWE is as follows:

\documentclass{article}
\usepackage{unicode-math}
\setmathfont{latinmodern-math.otf}


\begin{document}
$\aleph,\beth,\gimel,\daleth$ 
\end{document}

Compile it with XeLaTex, we have

The last three symbols are clearly different from ones in the amssymb package. This is come from Heiko Oberdiek. But I don't want to use unicode-math and not want to use other symbols form latin modern math. So is there any way to invoke aleph, beth, gimel and daleth symbols only and not to invoke other letters or symbols in the latin modern math font? Any idea is appreciated.

  • Is loading the amssymb package permitted? Please also clarify what you mean by "invoke". Do you maybe mean, "load a (font) package"?

    @Mico It's better not to call amssymb. But amssymb could be also permitted.

  • Thanks. Good to know. I would argue that it's not easy to try to do serious math typesetting without the amsmath and amssymb packages...

  • It is not at all clear what you want here, latin modern doesn't have beth gimel or daleth, like computer modern it only has aleph. Commented Aug 22, 2021 at 10:33

    oh so you are using xelatex or lualatex not pdflatex (that certainly was not clear before) Commented Aug 22, 2021 at 10:43

It seems that you want something like the following

\documentclass{article}

\usepackage{fontspec}
\newfontfamily\lmotf{latinmodern-math.otf}

\DeclareMathAlphabet{\mathlmotf}{TU}{latinmodern-math.otf(0)}{m}{n}

\def\aleph{\mathlmotf{^^^^2135}}
\def\beth{\mathlmotf{^^^^2136}}
\def\gimel{\mathlmotf{^^^^2137}}
\def\daleth{\mathlmotf{^^^^2138}}


\begin{document}

$\aleph,\beth,\gimel,\daleth$ 
\end{document}

Which makes

  • @M.Logic mathspec loads fontspec so you are already using fontspec Commented Aug 22, 2021 at 11:20
