Foreign symbols, and letters

Hi guys,

I've searched the boards a bit, without luck - i hope you can help me.

I'm loading in a HTML-page with simple english first:
My cat is called "ninja". It's green.

The '-symbol and "-symbol gets replaced by a weird �-symbol.

The same with the danish letters: ÆØÅ.

It's a bit weird tho, due to it's being perfectly shown, when opened in a webbrowser.

The way im getting the HTML, inside the FCKeditor:

$oFCKeditor->Value = file_get_contents($_GET["doc"]);

edit.php?doc=whatever.html

I'm not a shark at php, but i'm learning, so be gentle .

Edit:

I dunno if it's to some help, but i did some testing. Made a test.php, with the:
echo file_get_contents($_GET["doc"]);

No problems there... showed perfectly in the browser.

Edit edit:
So sorry for double post, i couldn't move the topic here.
Hope for your understanding.
