当其他字体中不存在倾斜版本时，如何赋予符号数学倾斜以使其看起来像数学符号？

Question

\documentclass{minimal}
\usepackage{skull}
\begin{document}
I want $\skull$ to have a slight slant to it when 
used in math mode.  Other than editing the font, 
how can I achieve this?  There are no other fonts 
that I know of that have a slanted version of the 
$\skull$ symbol.
\end{document}

Answer 1

或许

\newcommand\fakeslant[1]{\pdfliteral{1 0 0.167 1 0 0 cm}#1\pdfliteral{1 0 -0.167 1 0 0 cm}}
\newcommand*\slskull{\fakeslant{\skull}}
