Maybe this leads to an Adobe ISO Latin-1 encoding for GNU Emacs…
I copied off PLRM the encoding from page 605 and pasted into *scratch* buffer.
In rectangular editing mode I reconstructed this table:
octal 0 1 2 3 4 5 6 7
------------------------------------------------------------------
\04x ! " # $ % & ’
\05x ( ) * + , - . /
\06x 0 1 2 3 4 5 6 7
\07x 8 9 : ; < = > ?
\10x @ A B C D E F G
\11x H I J K L M N O
\12x P Q R S T U V W
\13x X Y Z [ \ ] ^ _
\14x ‘ a b c d e f g
\15x h i j k l m n o
\16x p q r s t u v w
\17x x y z { | } ~
\20x
\21x
\22x ı ` ́ ˆ ̃ ̄ ̆ ̇
\23x ̈ ̊ ̧ ̋ ̨
\24x ¡ ¢ £ ¤ ¥ ¦ §
\25x ̈ © ª « ¬ - ® ̄
\26x ° ± ² ³ ́ μ ¶ ·
\27x ̧ ¹ º » ¼ ½ ¾ ¿
\30x À Á Â Ã Ä Å Æ Ç
\31x È É Ê Ë Ì Í Î Ï
\32x Ð Ñ Ò Ó Ô Õ Ö ×
\33x Ø Ù Ú Û Ü Ý Þ ß
\34x à á â ã ä å æ ç
\35x è é ê ë ì í î ï
\36x ð ñ ò ó ô õ ö ÷
\37x ø ù ú û ü ý þ ÿ
This was easy, each column is 27 lines high. So I could easily move, cut, and
put.
In Wikipedia I went to "edit" the table. So I could copy the source code and
paste it into *scratch* buffer. The lines started with some rubbish which ended
in the reg-exp "[lr]l|". SO I could turn "^.*[rl]l|" → "". I sorted the lines
in order remove all lines containing no context. On what was left I could
sort-regexp-fields the complete lines on "|[0-9]+}}$". So the list was sorted.
In column 64 I added in rectangular mode "• " because "•" is not encoded. A
copy of the table above was stripped off the left-most column all TABs were
converted into LINEFEEDs. By removing the empty lines I had a "vector" which I
could easily move right of "• ". The result is:

It looks as if both tables (PLRM and Wikipedia) describe the same encoding. To
have a proof I took a copy of this table and cut the "vector" at the right edge
and put it below the table, between them a separating line of plus signs. From
the remainder of the table I could delete all from "]]" to "$", and then all
from"^" to "|". The remaining "[[" pairs could be removed. I split the window
into two and invoked compare-windows. Of course it choked a few times because
some characters are in HTML notation, but it proved that both encoding vectors
are actually the same.
So I presume the data above can be used for the Adobe Standard ISO Latin-1
encoding. (After some further editing.)

It is so hot in some places that the people there have to live in other places.
