\section{Default}
This section gives various tables which are in the default font and
encoding.

\All

\section{Times}
Now we change the encoding, and should start setting the
same tests in Times Roman, Helvetica and Courier.

\makeatletter
\Sansfont{phv}
\Romanfont{ptm}
\Typewriterfont{pcr}
\Encoding{T1}
\selectfont
\All

\section{Switch back to CMR and OT1}
Now we switch back to the original CM font and encoding, and check
to see if the tests still give the same result.

\fontencoding{OT1}\CMRdefaults\selectfont
\All

\section{Bits from all types of encoding}
In this section, we switch from Roman to Sans to Typewriter, each one
of which is a font with a different encoding.

\subsection{Roman font cmr, encoding OT1}
\Romanfont[OT1]{cmr}\rm\Accents\Specialchars

\subsection{Sans font cmss, encoding T1}
\Sansfont[T1]{cmss}\sf\Accents\Specialchars

\subsection{TT font pcr, encoding OT1}
\Typewriterfont[OT1]{pcr}\tt\Accents\Specialchars

\subsection{Combined}
Finally, we present some running text in three different roman fonts,
each with a different encoding.

\Romanfont[OT1]{cmr}\rm This is CMR and OT1 encoding. \Sample
\Romanfont[OT1]{ptm}\rm This is Times Roman and OT1 encoding. \Sample
\Romanfont[T1]{cmr}\rm This is CMR and T1 encoding. \Sample
