使用最近的字体规范将标点符号大小与小型大写字母匹配

Question

我重新参与了以下讨论： 将标点符号大小与小型大写字母匹配 James Ashton 提出的有趣解决方案“使撇号成为一个活动字符，并将其定义为仅在小型大写字母有效时使用 \raisebox”不再适用于较新版本的 fontspec，因为此选项具有全局作用（如以下讨论所述：新版本的 fontspec 给出 WordSpace 错误)。我发布了一个（几乎）MWE，但它不起作用；目的是创建一个“临时”小写字体。我无法更改代码来调整它。有人有解决方案吗？谢谢

这不适用于\scshape，但我不认为您需要它。

\documentclass[a4paper,12pt]{report}
\usepackage{fontspec}
\usepackage{polyglossia}
\usepackage{xparse,l3regex}

\setmainfont{EB Garamond}[
  Scale=1.1,

\newfontfamily{\spacedcaps}{EB Garamond}[
  Scale=1.1,
  Letters={UppercaseSmallCaps,SmallCaps},
  LetterSpace=2,
  WordSpace=1.2,
]

注意，和都'可以’使用，并且会降低。处理其他引号也很容易。
