What see is the 'translation' of some ISO Latin encoding into UTF-8 and 
then displaying these double byte values as unibytes!

This could explain a bit:

First column contains the glyphs as they are, next columns have the 
glyph's byte value expressed as octal, decimal, or hexadecimal 
numerals. Next column, UCS2, show the slot number (ASCII code) of that 
glyph in Unicode (which, I think, is too the internal representation in 
GNU Emacs). The next column now shows into which bytes the glyphs from 
column 1 are translated as UTF-8. As you can see you can 'see' the 
UTF-8 bytes as 'normal' characters, a UTF-8 encoded æ is just 'ÄĻ' if 
displayed in ISO Latin-4, 'Ħ' in ISO Latin-1 ...

So, to conclude: your Emacs obviously saves your input as UTF-8, and 
you have to make the buffer display in UTF-8 too! The correct headers 
would look like

        ;;; -*- mode: Text; coding: utf-8; -*-

Once you have the file opened in the wrong encoding you can change that 
with revert-buffer-with-coding-system, C-x RET r utf-8 RET.

Have you thought of

(prefer-coding-system     'utf-8-unix)

Could be it cures a lot. There is too (set-language-environment  
'Danish) ...
