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

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.

function color($string)
{
	$string = iconv('ASCII', 'UTF-8//IGNORE', $string);
	$pattern = '/([0-9]{3})([0-9]{3})([0-9]{3})/i';
	$replacement = '<span style="color: rgb(${1}, ${2}, ${3});">';
	$html = preg_replace($pattern, $replacement, $string);
	if (!$html) {
		return $string;
	} else {
		return $html . '</span>';
	}
}

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.
