Scaling problem with fontspec package and \footnote.

Question

footnote does not scale properly with using fontspec. Any idea how to solve this problem? Already tried realscripts and xltxtra but no luck. Thanks,

\documentclass[12pt]{article} 
\usepackage[english]{babel} 
\usepackage{fontspec} 
\setmainfont{Times New Roman} 
\newcommand{\phont}[1]{\fontspec[Scale=#1]{Times New Roman}} 

\begin{document}\noindent 

{\phont{1} test\footnote{test}}\\ 
{\phont{2} test\footnote{test}}\\ 
{\phont{3} test\footnote{test}}\\ 
{\phont{1}test\textsuperscript{1}}\\ 
{\phont{2}test\textsuperscript{2}}\\ 
{\phont{3}test\textsuperscript{3}} 

\end{document}

Answer 1

It's "by design". LaTeX's \footnote sets its footnote mark in font \normalfont. However you want the current text font. \textsuperscript keeps the current font except the font size.

The behaviour of LaTeX can be changed by redefining \@makefnmark:

\documentclass[12pt]{article}
\usepackage[english]{babel}   
\usepackage{fontspec} 
\setmainfont{Times New Roman}
\newcommand{\phont}[1]{\fontspec[Scale=#1]{Times New Roman}}

\makeatletter
\renewcommand*{\@makefnmark}{%
  \hbox{%
    \@textsuperscript{%
      % \normalfont % removed
      \selectfont % added
      \@thefnmark
    }%
  }%  
}   
\makeatother

\begin{document}

\vspace*{\fill}

\noindent
{\phont{1} test\footnote{test}}\\
{\phont{2} test\footnote{test}}\\
{\phont{3} test\footnote{test}}\\
{\phont{1}test\textsuperscript{1}}\\
{\phont{2}test\textsuperscript{2}}\\
{\phont{3}test\textsuperscript{3}}  

\end{document}
