列表显示斜体引号 - 如何以常规形式打印它们？

Question

我使用该listings包来显示源代码。我刚刚意识到，双引号和单引号打印在斜体- 应打印在常规的相反...问题出在哪里？是否有我忽略的配置？

有什么想法吗？感谢您的意见！

我定义了自己的列表样式如下：

\definecolor{codegreen}{rgb}{0,0.6,0}
\definecolor{codegray}{rgb}{0.5,0.5,0.5}
\definecolor{codepurple}{rgb}{0.58,0,0.82}
\definecolor{backcolour}{HTML}{F5F5F5}

\lstdefinestyle{codestyle}{
    backgroundcolor=\color{backcolour},   
    commentstyle=\color{codegreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{codegray},
    stringstyle=\color{codepurple},
    basicstyle=\ttfamily,
    breakatwhitespace=false,         
    breaklines=true,                 
    captionpos=b,                    
    keepspaces=true,                 
    numbers=left,                    
    numbersep=5pt,                  
    showspaces=false,                
    showstringspaces=false,
    showtabs=false,                  
    tabsize=2
}

\lstset{style=codestyle}

我还加载了 Jetbrains-MonoFont（可以下载这里)：

%JetBrains Mono-Font für Code
\setmonofont{JetBrains Mono}[
    Path = ./Fonts/Code/,
    Extension = .ttf,
    UprightFont = *-Regular,
    BoldFont = *-Bold,
    ItalicFont = *-Italic,
    BoldItalicFont = *-BoldItalic,
    Contextuals = Alternate,
    Ligatures = TeX,
]
\lstset{
    basicstyle = \ttfamily,
    columns = flexible,
}
\makeatletter
\renewcommand*\verbatim@nolig@list{}
\makeatother

引号不是斜体打印的，而是被替换为”（右双引号，U+201D）。这是因为您被告知fontspec要为等宽字体启用 TeX 连字，而这些所谓的连字之一正是进行这种替换的。字符(U+201D) 在您选择的字体中呈现为倾斜的引号（不仅如此）。和（右单引号，U+2019）也是”如此。'’

如果注释掉 选项Ligatures = TeX，\setmonofont您将得到以下输出：
