I have upload a cn.php file in thread translation. And I find a problem about it. As I change the language file to cn.php file,everything is ok except those rrd graphs.All Chinese charaters showed in a messy way.I know GD does not support Chinese characterset but can support utf8.So I change those characters to be showed in rrd graphs from GB2312(Chinese characterset) to utf8.But there is still no change,just other messing words.Any suggestion?
