Encoding of the dedicated server/game

Hi,
I am creating a quick RCon Terminal in PHP and kind of it works fine. But I met some issues with the colors because of the encoding. (Even though the PHP/HTML file has the right encoding set)
The output can be seen here which is not good:
Wonder if this related to the encoding or the RCon PHP itself.
Any suggestions?

use \169 instead the copyright char.
example for white: \169255255255
example for white: \169255255255

By the looks of it, you need to convert from Windows-1252 to UTF-8. However, if you want to display colors then that's another story.

No of course, I meant the encoding, the color code I know it's different 
as I have to search for the output content and then change things accordingly.

Hajt, you are a god, thanks a lot. I promsie not to forget this. For some reason it does not work tho. It appears to be still something with the encoding, I believe.
