Gzip html文件显示chrome中的怪异字符

Question

在我的php输出上使用gzip，就像这样

if( isset($compression['html']) && $compression['html'] == TRUE)
{
ob_start("ob_gzhandler");   
header("cache-control: must-revalidate");
header("expires: ".gmdate('D, d M Y H:i:s', time() + $compression['expire'])." GMT");
}

生成错误显示在下图中。它在FF和Safari中工作正常，但在chrome中却没有。知道怎么解决吗？

这是我得到的标题
