在 tikz 节点中绘制一条跨基线的线

Question

我想画一条线来显示以下节点的基线

\begin{tikzpicture}[remember picture,overlay]
\node[font={\fontsize{40}{42}\selectfont},
     above]
     at (current page.south)
     {Quaestor};
\end{tikzpicture}

我怎样才能做到这一点？

\documentclass{article}
\usepackage{tikz}


\begin{document}
\begin{tikzpicture}[remember picture,overlay]
\node[font={\fontsize{40}{42}\selectfont},
     above]
      (a)
     at (current page.south)
     {Quaestor};
\draw[red](a.base west)--(a.base east);     
\end{tikzpicture}
\end{document}
