fontspec：更改数字样式也会影响字母

Question

我想使用带衬线数字的小型大写字体。为此，我设置了SmallCapsFeatures = { Numbers = Lining }。但是，这样，字母就不再是小型大写字母了。有没有办法设置数字的样式而不影响字母？

下面是 MWE。

\documentclass{article}

\usepackage{fontspec}

\setsansfont{SourceSansPro-Regular.otf}
    [
      Scale          = MatchLowercase ,
      BoldFont       = SourceSansPro-Bold.otf ,
      ItalicFont     = SourceSansPro-RegularIt.otf ,
      BoldItalicFont = SourceSansPro-BoldIt.otf ,
      SmallCapsFeatures = { Numbers = Lining } ,
      BoldFeatures   = {
        SmallCapsFeatures = { Numbers = Lining } ,
      }
    ]


\usepackage{blindtext}

\begin{document}

\sffamily

{\scshape A0b1c2d3}

{\bfseries\scshape A0b1c2d3}

{\bfseries A0b1c2d3}

\end{document}

Answer 1

简短答案

SmallCapsFeatures = { Numbers=Lining, Letters=SmallCaps }

较长的答案

默认情况下，SmallCapsFeatures激活Letters=SmallCaps（该smcp功能）。SmallCapsFeatures=手动设置可覆盖该功能。您需要同时启用两者。

\documentclass{article}

\usepackage{fontspec}

\setsansfont{SourceSansPro-Regular.otf}
    [
      Scale          = MatchLowercase ,
      BoldFont       = SourceSansPro-Bold.otf ,
      ItalicFont     = SourceSansPro-RegularIt.otf ,
      BoldItalicFont = SourceSansPro-BoldIt.otf ,
      SmallCapsFeatures = { Numbers = Lining, Letters=SmallCaps } ,
      BoldFeatures   = {
        SmallCapsFeatures = { Numbers = Lining, Letters=SmallCaps } ,
      }
    ]


\usepackage{blindtext}

\begin{document}

\sffamily

{\scshape A0b1c2d3}

{\bfseries\scshape A0b1c2d3}

{\bfseries A0b1c2d3}

\end{document}

Answer 2

以下示例对我有用，可生成 SmallCaps 和内衬数字。正如 Thérèse 所说，它们是默认使用的。

\documentclass{article}
\usepackage{fontspec}

\setsansfont{SourceSans3-Regular.otf}
[     Scale          = MatchLowercase ,
      BoldFont       = SourceSans3-Bold.otf ,
      ItalicFont     = SourceSans3-It.otf ,
      BoldItalicFont = SourceSans3-BoldIt.otf ,
]

\begin{document}

\sffamily

{\noindent\scshape Regular SmallCaps \quad A0b1c2d3 } \newline
{\bfseries\scshape Bold SmallCaps \quad A0b1c2d3}\newline
{\bfseries Bold No Caps \quad A0b1c2d3}

\end{document}
