使用 LuaLaTeX 和 fontspec 时重新定义标准字体大小命令

Question

如何在使用 LuaLaTeX 和 fontspec 时重新定义标准字体大小命令（、、\small等）？\normalsize\large

根据我在网上搜索到的内容，我做了以下事情：

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Calibri}
  \renewcommand{\footnotesize}{\fontsize{9bp}{11bp}\selectfont}
  \renewcommand{\small}{\fontsize{10bp}{12bp}\selectfont}
  \renewcommand{\normalsize}{\fontsize{11bp}{13bp}\selectfont}
  \renewcommand{\large}{\fontsize{13bp}{15bp}\selectfont}
\usepackage{soul}

\begin{document}
% HEADING
\begin{flushleft}\small
  Keywords: some, relevant, words, here.
\end{flushleft}
\begin{center}\large
  \textbf{The title is very important}\\[1ex]
  \ul{A. U. Thor}\footnote{An address, Country}
\end{center}

% MAIN TEXT
filler filler filler filler filler filler filler filler

filler filler filler filler filler filler filler filler filler 
filler filler 
\end{document}

使用我安装的 Calibri 字体，编译效果确实很好。但是，我收到以下警告（如果不存在重新定义则不会出现）：

我认为

1. 不应存在​​对lmr和的引用，并且cm
2. 应该有一种方法可以获得（更接近）我要求的实际尺寸。

Calibri(1)由于字体系列未定义，因此您的示例未产生有关警告。

关于数学字体的警告是意料之中的；您可以通过加载来删除它们fix-cm。

\footnotesize标准 10pt 选项中的定义是

% size10.clo, line 66:
\newcommand\footnotesize{%
   \@setfontsize\footnotesize\@viiipt{9.5}%
   \abovedisplayskip 6\p@ \@plus2\p@ \@minus4\p@
   \abovedisplayshortskip \z@ \@plus\p@
   \belowdisplayshortskip 3\p@ \@plus\p@ \@minus2\p@
   \def\@listi{\leftmargin\leftmargini
               \topsep 3\p@ \@plus\p@ \@minus\p@
               \parsep 2\p@ \@plus\p@ \@minus\p@
               \itemsep \parsep}%
   \belowdisplayskip \abovedisplayskip
}

如果您不需要脚注中的数学或列表或使用 的任何内容\footnotesize，您可以坚持仅对字体大小进行简单的重新定义。由于您设置的是 11bp 大小，因此使用 11pt 选项加载文章，然后修补以使用bp而不是是有意义的pt。

\documentclass[11pt]{article}
\usepackage{fontspec,fix-cm}

\usepackage{soul}
\usepackage{regexpatch}

\setmainfont{Calibri}

\makeatletter
\newdimen\bp@ \bp@=1bp
\xpatchcmd{\normalsize}{\@xipt{13.6}}{{11bp}{13bp}}{}{}
\xpatchcmd*{\normalsize}{\p@}{\bp@}{}{}
\xpatchcmd{\small}{\@xpt\@xiipt}{{10bp}{12bp}}{}{}
\xpatchcmd{\small}{\p@}{\bp@}{}{}
\xpatchcmd{\footnotesize}{\@ixpt{11}}{{9bp}{11bp}}{}{}
\xpatchcmd*{\footnotesize}{\p@}{\bp@}{}{}
\renewcommand\large{\@setfontsize\large{13bp}{15bp}}
\makeatother
