Subject: [PATCH] fixed issue #129
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

根据实验，在某些web服务器上，对`urlencode`也就是RFC 3986的标准解释不同，它们将unicode字符转义为以百分号开头的小写字符，而php中则默认为大写字符。比如“你好”在php中被转义为`%E4%BD%A0%E5%A5%BD`而在某些服务器上被转义为`%e4%bd%a0%e5%a5%bd`。
这导致`Widget_Archive`中的`checkPermalink`函数将它们识别为不同的路径，从而循环重定向。

解决方法：在`checkPermalink`函数中直接比较`urldecode`以后的`path`
