Option `cd2012ts` uses Open Sans instead of Univers

[mrpiggi]

When using the tud beamer theme with option cd2012ts, package tudscrfonts is loaded, which sets Open Sans as default since version v2.06. Maybe option cdoldfont should be passed to tudscrfonts in this case. This issue was already discussed in #28 but is actually off-topic.

% use lualatex for compilation
\listfiles
%\PassOptionsToPackage{cdoldfont}{tudscrfonts}
\documentclass{beamer}
\mode<presentation>
{
  \usetheme[cd2012ts]{tud}
}
\usepackage{fontspec}
\begin{document}
\begin{frame}{test}
	\(a \beta \Rightarrow\)
\end{frame}
\end{document}

Ok, now I understand. How do I find out whether tudscrfonts is older than 2.06? Or can I safely pass cdoldfont to tudscrfonts befor that version?

Well, actually I wouldn't as tudscrfonts is distributed via CTAN and it is easy to update. But if you really want to, you could do something like this (v2.06 was released with date 2019/06/28)

\RequirePackage{tudscrbase}[2019/06/28]
\@ifpackagelater{tudscrbase}{2019/06/28}{%
  \if@useUniversFont
    \PassOptionsToPackage{cdoldfont}{tudscrfonts}
  \fi
}{}
\RequirePackage{tudscrfonts}[2019/06/28]
