\usepackage{luatexja-fontspec}
\begin{document}
Lot's of Warnings.
\end{document}
上面的示例会抛出大量以下类型的错误
Package microtype Warning: Unknown slot number of character
(microtype) `\textgreater '
(microtype) in font encoding `EU2' in protrusion list
(microtype) `T1-default'.
目的是制作一份包含日语、中文、俄语、英语和德语的文档。对于支持它的语言，我希望微类型支持。这可能吗？luatexja 是这里正确的方法吗？
编辑：抱歉，我在这里遗漏了一条重要的话。
\documentclass{article}
\usepackage{luatexja-fontspec}
\setmainfont[Ligatures=TeX]{NimbusSansL.otf}
\usepackage{microtype}
\begin{document}
Lot's of Warnings.
\end{document}
答案1
下面的文档没有显示任何microtype警告，因为该包是在正确的时间加载的，即在字体相关包之后。
\documentclass{article}
\usepackage{luatexja}
\usepackage{microtype}
\begin{document}
No warning.
\end{document}
这是终端输出

正如您所见，也没有任何microtype警告。
现在，当您定义与默认字体不同的主字体时会发生什么？默认情况下，mt-LatinModernRoman.cfg会读入文件，其中包含字符继承和突出的指令。对于其他字体，如果没有相应的.cfg文件，则使用标准文件，其中包含一些对 LuaLaTeX 或 XeLaTeX 没有用的指令（例如所有重音字符）。
这些警告虽然无害，但却很烦人。你可以使用以下软件包来消除这些警告silence：
\documentclass{article}
\usepackage{luatexja-fontspec}
\usepackage{microtype}
\usepackage{silence}
\WarningFilter{microtype}{Unknown slot number of character}
\setmainfont{TeX Gyre Termes}
\begin{document}
No warning.
\end{document}
当然，避免警告的更好方法是提供适当的.cfg文件。
