\documentclass{article}
\usepackage[T1,OT1]{fontenc}
\def\OTIenc{OT1}
\begin{document}

\makeatletter
   \f at encoding:
  \ifx\f at encoding\OTIenc
   is defined
  \else
   is not defined
  \fi

\fontencoding{T1}\selectfont
OT1:
  \ifx\f at encoding\OTIenc
  is defined
  \else
  is not defined
  \fi

\end{document}
