我正在尝试使用 xeLaTeX...但我没有使用标准字体（拉丁现代字体或计算机现代字体？）获得粗体小写字体。
使用 LaTeX，我使用它来解决问题，因为我知道粗体小型大写字母不会与 lmodern 一起出现。
\usepackage{lmodern} \usepackage{fix-cm}
\rmfamily
\DeclareFontShape{T1}{lmr}{b}{sc}{<->ssub*cmr/bx/sc}{}
\DeclareFontShape{T1}{lmr}{bx}{sc}{<->ssub*cmr/bx/sc}{}
如何用 xeLaTeX 制作类似的东西？也许使用 cm-unicode（用于缺失的字体）？但我不明白该怎么做...
我已看到更多有关此问题的帖子，但没有给出解决方案。
谢谢。

我已经尝试使用 \setmainfont{CMU Serif} 但是收到错误：

l.14 \textbf{\textsc{bold small caps}}
I wasn't able to read the size data for this font,
so I will ignore the font specification.
[Wizards can fix TFM files using TFtoPL/PLtoTF.]
You might try inserting a different font spec;
e.g., type `I\font<same font id>=<substitute font name>'.

日志文件显示您正在“原始” TeX Live 上使用 XeLaTeX，但 CMU Serif 字体不可用作系统字体。
fc-cache -fsv单独运行是不够的，除非您还将 TeX Live 字体提供给fontconfig库。
这两个命令
> sudo cp $(kpsewhich -var-value TEXMFSYSVAR)/fonts/conf/texlive-fontconfig.conf /etc/fonts/conf.d/09-texlive.conf
> sudo fc-cache -fsv
应该可以满足您的需要。I>代表 shell 提示符。我们复制的文件09-texlive.conf包含/etc/fonts/conf.d
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/opentype</dir>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/truetype</dir>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/type1</dir>
</fontconfig>
但这并不重要。重要的是，完成该设置后，TeX Live 主树中的所有字体都将可用fontconfig，因此 XeTeX 也将能够通过字体名称而不是仅通过文件名来找到它们。
如果这不起作用，您可以随时通过文件名调用 CMU Serif：
\documentclass[11pt]{article}
\usepackage[tuenc]{fontspec}
\setmainfont{cmun}[
Extension=.otf,
UprightFont=*rm,
ItalicFont=*ti,
BoldFont=*bx,
BoldItalicFont=*bi,
]
\begin{document}
not bold or caps \textsc{small caps}
\textbf{bold} \textbf{\textsc{bold small caps}}
\textit{italic} \textsc{\textit{italic small caps}}
\textbf{\textit{bold italic}} \textbf{\textit{\textsc{bold italic small caps}}}
\end{document}
请注意，CMU Serif Italic 和 CMU Serif BoldItalic 没有小型大写字母字形，因此您会在第三行和第四行看到普通斜体和粗体小型大写字母。
如果建议的程序fc-cache成功，则代码
\documentclass[11pt]{article}
\usepackage[tuenc]{fontspec}
\setmainfont{CMU Serif}
\begin{document}
not bold or caps \textsc{small caps}
\textbf{bold} \textbf{\textsc{bold small caps}}
\textit{italic} \textsc{\textit{italic small caps}}
\textbf{\textit{bold italic}} \textbf{\textit{\textsc{bold italic small caps}}}
\end{document}
应该与 XeLaTeX 和 LuaLaTeX 一起工作。

这里给出的解决方案（适用于我的 ubuntu 2016）
将 texlive-fontconfig.conf 复制到 /etc/fonts/conf.d/09-texlive.conf
> sudo cp $(kpsewhich -var-value TEXMFSYSVAR)/fonts/conf/texlive-fontconfig.conf /etc/fonts/conf.d/09-texlive.conf
修改 /etc/fonts/conf.d/09-texlive.conf :(来源：http://www.tug.org/texlive/doc/texlive-en/texlive-en.html#x1-340003.4.4）
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/opentype</dir>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/truetype</dir>
<dir>/usr/local/texlive/2016/texmf-dist/fonts/type1</dir>
<selectfont>
<rejectfont>
<glob>/usr/local/texlive/2016/texmf-dist/fonts/type1/public/cm-unicode/*</glob>

</selectfont>
</fontconfig>

> sudo fc-cache -fsv
测试：
\documentclass[11pt]{article}
\usepackage[tuenc]{fontspec}
\setmainfont{CMU Serif}
\begin{document}
not bold or caps \textsc{small caps} \par
\textbf{bold} \textbf{\textsc{bold small caps}} \par
\textit{italic} \textsc{\textit{italic small caps}} \par
\textbf{\textit{bold italic}} \textbf{\textit{\textsc{bold italic small caps}}}
\end{document}
