In a document mostly in English and Sanskrit, I would like to display a few short strings in Chinese, a language apparently not supported by polyglossia, which I normally use for language switching commands. It appears that the xeCJK package is the recommended option for that. However, it seems to be messing up quotation marks:
\documentclass{article}
\usepackage{xeCJK}
\setCJKmainfont{Droid Sans Fallback}
\begin{document}
“test” ``test''
\end{document}
Now, this is probably a feature I don't understand, but the documentation is in Chinese. I wonder if it can be disabled? I would rather not want to switch back all my quotation marks to `` and ''.

\xeCJKDeclareCharClass{Default}{`“,`”}. – muzimuzhi Z Nov 06 '20 at 21:33
