在一个目的完全不同的测试文件中，我发现自己面前出现了一条我不知道如何解释的通知。我查看了 polyglossia 文档（其中朗塔格不存在），在网上我只找到这个链接（最后一篇文章） 光泽乳胶警告 这似乎已经解决了 使用 lcscript 进行拉丁语检查 代码如下：
\begin{filecontents*}{\jobname.bib}

journal = {La Matematica nella Società e nella Cultura},

但是，我收到：
Package polyglossia Warning: Asking to add empty feature to latin font (Languag
e="Italian" to langtag "") on input line 11.
)
Package polyglossia Warning: Asking to add empty feature to latin font (Languag
e="Italian" to langtag "") on input line 73.
我的代码有什么错误或缺失吗？是多语问题吗？请注意，我有 Texlive2019，始终更新。谢谢
答案1
问题在于你使用了\PolyglossiaSetup。此命令会重新初始化语言，因此你会丢失在 gloss-ldf 中完成的所有设置。添加或更改键的正确命令是\SetLanguageKeys。一个直观的例子是 frenchspacing 设置，你也会使用 丢失它\PolyglossiaSetup：
\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{italian}
%\PolyglossiaSetup{italian}{indentfirst=false} %wrong
\SetLanguageKeys{italian}{indentfirst=false}
\begin{document}
abc. Abc
\nonfrenchspacing
abc. Abc
\end{document}
