In emacs how do you enter special characters (like « odr §) for which there 
is no key on your keyboard? Is there anything like the Alt-<ISO-Nr.> 
function in Windows?

C-q takes octal arguments.

There are some input methods in GNU Emacs, you can hold down AltGr  
(or such) while pressing other keys – and it works to enter C-q  
<octal value> <some non-digit>. By changing read-quoted-char-radix  
(this can be done via the customisation interface) to be 16 you can  
insert any Unicode character by its number.

Great!
BTW I have Emacs 21.3 under Windows. Any chance I teach it to take 
Alt-NumericKeypad sequences?

Is this octal ASCII--or what?  I would like to google for a list of
the characters and their octal numbers, but i don't know what the
encoding is.  Or is this a big can of worms i should forget about?

It takes octal arguments - to insert a German "ss", just use C-q
0-3-3-7-return - six keystrokes, and you should get a ß inserted at the point.
(You won't get anything printable for 0000 octal through 0037 - 0040 is
a space, though - and from 0200 through 0237 (128 through 159 in decimal).)

To what do these numbers corelate, and is there a list somewhere with
which i can look up specific ones?

it may be more practical to use an input method that provides what you
need. see the function toggle-input-method and the variable
default-input-method. for example, i use the input method latin-9-prefix,
which gives me several dead keys. then "a gives ä, ~o gives õ, etc. "s
gives ß, ~< gives «, /a gives å. you may find an input method that suits
your needs.

They are the emacs codes corresponding to the character.  Fortunately,
for characters in the iso-8859-1 character set (including ASCII), the
emacs encoding are the same as the iso-8859-1 encoding.  But for other
unicode characters, the emacs codes are different.  You'd have to read
emacs doc or sources to know what they are or how they map from
unicode to emacs, I guess.

You can set the variable read-quoted-char-radix to specify the base
C-q takes its number, (At least in emacs-version "22.0.94.1"), so you
don't have to convert from decimal to octal in your head.

You can find the iso-8859-1 coding table in wikipedia and numerous
other web sites, use google.

The octal numbers are for entering special characters in the ISO-8859-1
character set, which is an 8-bit code.  Other character sets may not follow
that rule.
