Special charecters doesn't work

I have a webpage with the special charecters working on: http://ift.tt/1E61zyg

But with the exactly the same code on another page it does not work: http://ift.tt/1M8TgtG

I know that there is a solution where i can put code in that makes the charecter, such as Ø, Å etc.

But i want to avoid using these since it would take a long time to switch out all "æ, ø, å" charecters with the codes.

My charset is defined in my .htacces file, which looks like this;'

DirectoryIndex index.php index.html index.htm

Options -Indexes
Options +FollowSymlinks

<Files .htaccess>
deny from all
</Files>

php_value include_path ".:/usr/www/gtgmodweb/public/inc"

ErrorDocument 404 http://ift.tt/1M8TiBz
ErrorDocument 403 http://ift.tt/1E61zyk

If anyone has a clue on what causes the page to not displaying the charecters correctly, then please help me solving it!
