There is no ♯ (\sharp) , ▿ (\triangledown) in font Garamond-Math

[Mariusz-W]

Some symbols missing that appear in advanced Mathematics. I got the corresponding messages about the missing characters when processing notes of my lectures.

The symbols \flat and \natural are also missing. It seems that \triangledown is already missing from unicode-math. As a workaround the missing symbols (excluding \triangledown) can be loaded from another font.

Minimal example including the workaround.

% !TEX program = lualatex
\documentclass{article}
\usepackage{unicode-math}

\begin{document}
  \textbf{default font}\\
  \textbackslash flat $\flat$\\
  \textbackslash natural $\natural$\\
  \textbackslash sharp $\sharp$\\
  \textbackslash triangledown $\triangledown$
  \vskip1cm
  
  \setmathfont{Garamond-Math}
  \textbf{Garamond-Math}\\
  \textbackslash flat $\flat$\\
  \textbackslash natural $\natural$\\
  \textbackslash sharp $\sharp$\\
  \textbackslash triangledown $\triangledown$
  \vskip1cm
  
  \setmathfont{Latin Modern Math}[range={\sharp, \natural, \flat}]
  \textbf{Workaround}\\
  \textbackslash flat $\flat$\\
  \textbackslash natural $\natural$\\
  \textbackslash sharp $\sharp$\\
  \textbackslash triangledown $\triangledown$

\end{document}
