关于wordpress解决中文化路径的问题

wordpress设定Permalink后一个最大的问题是中文不正常，主要原因是IIS解释路径是GBK编码，转给wordpress按UTF-8取值就不对了。

解决办法

打开wp-includes/classes.php文件，找到(大约在154行)

if ( isset($_SERVER['PATH_INFO']) )
 $pathinfo = $_SERVER['PATH_INFO'];
else
 $pathinfo = '';
$pathinfo_array = explode('?', $pathinfo);
$pathinfo = str_replace("%", "%25", $pathinfo_array[0]);
$req_uri = $_SERVER['REQUEST_URI'];

修改为：

if ( isset($_SERVER['PATH_INFO']) )
 $pathinfo = mb_convert_encoding($_SERVER['PATH_INFO'], "UTF-8", "GBK");
else
 $pathinfo = '';
$pathinfo_array = explode('?', $pathinfo);
$pathinfo = str_replace("%", "%25", $pathinfo_array[0]);
$req_uri = mb_convert_encoding($_SERVER['PATH_INFO'], "UTF-8", "GBK");

改好后保存上传，再打开中文路径就OK了。
