pdf(la)tex
是否可以在文档主体中测试当前字体 (和)是否支持小写字母xe(la)tex
?我想要做的是:
\usepackage{xifthen}
...
\ifthenelse{<small caps are available with the current font>}{%
\textsc{my text}%
}{%
\uppercase{my text}%
}

好的,正如 David 在评论中指出的那样,仅仅查看\f@encoding/\f@family/\f@series/sc
是不够的,因为此命令是在替换期间定义的。因此,可能需要记录是否发生了替换:
\documentclass[11pt,a4paper]{scrartcl}
\makeatletter
\def\define@newfont{%
\begingroup
\let\typeout\@font@info
\escapechar\m@ne
\expandafter\expandafter\expandafter
\split@name\expandafter\string\font@name\@nil
\try@load@fontshape % try always
\expandafter\ifx
\csname\curr@fontshape\endcsname \relax
\expandafter\gdef\csname \curr@fontshape/sub\endcsname{}% new
\wrong@fontshape\else
\extract@font\fi
\endgroup}
\newcommand\testsc{%
\ifcsname \f@encoding/\f@family/\f@series/sc/sub\endcsname
no
\else
\ifcsname \f@encoding/\f@family/\f@series/sc\endcsname yes \else no \fi
\fi
\textsc{Aa}}
\makeatother
\begin{document}
\testsc
\bfseries \testsc
\scshape \testsc
\end{document}

除了修补之外,\define@newfont
还可以修补\wrong@fontshape
:
\usepackage{etoolbox}
\makeatletter
\preto\wrong@fontshape{\expandafter\gdef\csname \curr@fontshape/sub\endcsname{}}
....
