Actually, the default font encoding _is_ the StandardEncoding (8a), even if
not all the glyphs in that encoding vector are present in the font.

In fact it seems to depend on the version what the font contains. The PFA
(well, actually it's an LWFN, but those are equivalent) I've got is from
1989, has version 001.000, and does not contain lower case glyphs, but the
AFM I've got is from 1994, has version 001.002, and lists metrics also for
lower case glyphs.

The titling capitals are a bit lighter than the regular capitals, so I
suspect this could lead to a visual clash similar to that one gets with
faked smallcaps.

There are no kerns for the lower case glyphs, which makes it likely that
even the newer version of the font is mainly intended for all-caps usage.

I made an installation of this font as an all-caps font a couple of years
ago. Then I (roughly) used the command

 \installfont{padrd8t}{padrd8r,latin,vcenter}{t1maj}{T1}{pad}{m}{tl}{}

where t1maj.etx (maj for majuscles) says

\relax
\encoding

% We define the parameters for t1.etx to produce an all-caps font.
\setcommand\lc#1#2{#1}
\setcommand\uc#1#2{#1}
\setcommand\lclig#1#2{#1}
\setcommand\uclig#1#2{#1}
\setcommand\digit#1{#1}

% Then we call t1.etx.
\inputetx{t1}

\endencoding

and vcenter.mtx contains the commands

\relax
\metrics
