您可以为括号使用不同的符号字体。请注意,数学字体的数量是有限的,因此不应过度使用。该示例仅更改了右括号以演示差异:
\documentclass{report}
\usepackage[utopia]{mathdesign}
\DeclareSymbolFont{kpoperators}{OT1}{jkp}{m}{n}
\DeclareSymbolFont{kplargesymbols}{OMX}{jkp}{m}{n}
%\DeclareMathDelimiter{(}{\mathopen} {kpoperators}{"28}{kplargesymbols}{"00}
\DeclareMathDelimiter{)}{\mathclose}{kpoperators}{"29}{kplargesymbols}{"01}
\begin{document}
$2(a+b) \left(\rule{0pt}{1cm}\right)$
\end{document}
