SmallCaps 无法与 Ubuntu 字体兼容

我尝试使用该Ubuntu字体打印 SmallCaps 格式的文本，但是它不起作用。

代码：

% !TeX program = lualatex
\documentclass[ebook,11pt,twoside,openright,showtrims]{memoir}
% -------------------------------------------------------Packages
\usepackage{fontspec}
\usepackage{xcolor}  

\begin{document}

    \mainmatter
    
    \setmainfont{Ubuntu}    
    \textsc{Lorem not working}
    
    \scshape{Lorem not working}

    \setmainfont{Free Sans} 

    \textsc{Lorem working}

    \scshape{Lorem working} 
    
\end{document}

输出

在此处输入图片描述

日志中说 Ubuntu 有小型大写字母，那么为什么它不起作用呢？

如果我运行简化代码（通过文件名选择字体，因为我没有将其安装为系统字体，但这无关紧要）

\documentclass{article}
\usepackage{fontspec}

\setmainfont{Ubuntu}[
  Extension=.ttf,
  UprightFont=*-Regular,
  BoldFont=*-Bold,
  ItalicFont=*-Italic,
  BoldItalicFont=*-BoldItalic,
]

\begin{document}

\textsc{Lorem not working}
    
\end{document}

我在日志文件中看到

(fontspec)             - 'bold italic small caps'  (b/scit) with NFSS spec.:

但是也

LaTeX Font Warning: Font shape `TU/Ubuntu(0)/m/sc' undefined

scmp它只是告诉你该字体没有功能。以下信息证实了这一点otfinfo：
