Windows系统IIS环境，Wordpress在对中文TAG标签不能正常解析，导致所有带中文的链接全部失效。出现这个问题的原因是GBK编码与UTF-8编码的解析问题，我们可以通过修改Wordpress的classes.php文件来解决，打开wp-includes\classes.php文件。
if ( isset($_SERVER['PATH_INFO']) )
$pathinfo = $_SERVER['PATH_INFO'];
else
$pathinfo = '';
$pathinfo_array = explode('?', $pathinfo);
$pathinfo = str_replace("%", "%25", $pathinfo_array[0]);
$req_uri = $_SERVER['REQUEST_URI'];
替换为
if ( isset($_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['REQUEST_URI'], "UTF-8", "GBK");
