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.
