As per the documentation for those variables, you can't just set them
like that. Also, I think you want them both set to t, otherwise you
will have problems writing files in various encodings, due to the
buffer representation being a different encoding than what you are
trying to save as. You probably need to kill existing buffers and
reread the files after changing unify-8859-on-decoding-mode, since it
only has any effect when reading files/process output etc.

This is probably because those characters pass through
unify-8859-on-encoding-mode to convert them to Latin-1 after the
message has already been displayed. Out of the box, ps-print only
handles Latin-1, but there are variables to control this.

I think the change you are talking about was when saving a file. The
code for printing is different, so a separate fix will be required
there.

Using Unicode in Emacs will not magically fix postscript. There is
more work involved in getting all the peripheral code like ps-print to
take advantage of the Unicode support in the core of Emacs 23 than
there is in fixing a few minor bugs in Emacs 22.
