I will be happy to help correcting the norwegian translation.
There is also a problem with the display of headlines in norwegian. Letters Æ, Ø and Å does not display as letters, but as strange signs.

Can you try replicating the strange character problem on the live demo here?

Here is an example in "real life" (disregard fonts, lay out and so on)
http://fotouniverset.no/Best_Bygg/architecture2/architecture2/test2.php

The site content and news article is showing correctly, but the headline is not.

It shows up correctly here: http://network-13.com/news/
But not on my site when I include the
<?php
include 'news/index.php';
?>

I had the same problem with ä and ö. I have the news system on my front page which uses PHP. Other pages on my site are HTML. In HTML pages the UTF-8 charset worked with ä and ö but the PHP page didn't show them correctly with UTF-8. So, I changed the PHP page's charset to ISO-8859-1 and it worked. The ä and ö were showing. Everything went fine until I added the N-13 News to that PHP front page. Otherwise the ä and ö were working on the page but not in the headlines of the news.

Sollution: I use notepad when I edit the pages. The index.php had to be saved as in "UTF-8" coding instead of "ANSI" in the worpad. After doing this to the index.php both the news system and other part of the page started to show ä and ö correctly!

Hope this helps you :) And I also hope that the text here was understandable :D
