我的文档中有类似的内容print('abc')，但它变成了print(’abc’)（注意改变的引号），这会破坏编译。
我怎样才能使环境\begin{codeexample}和\begin{verbatim}（奖励）打印出真实的引文？（请注意，我仍然希望源包含真实的引文'，因为我仍然希望能够从比 PDF 更可靠的源文件中复制/粘贴内容）。

\documentclass[a4paper,doc2]{ltxdoc} % doc2 is needed to force the old version, or links get colored in a weird red way even with hidelinks. https://github.com/latex3/latex2e/issues/822
