网友回复:我读出来是%u9996%u9875...之类的不是$str = "张三";
网友回复:md("%u9996%u9875...")试试
网友回复:我的天哪，加密也行吗？？

javascript:alert(unescape('%u9996%u9875'));
此代码浏览器地址栏运行即可...
那个是escape转换过的代码.
所以用unescape转回来就可以了.
网友回复:晕..PHP版...
那个...
9996是unicode编码...
首先把它转换成10进制,然后在对照unicode表转成值就可以了.
过程是这样滴.

网友回复:9996是16进制的unicode编码...
网友回复:php中转换的！！我用iconv转怎么不行啊

网友回复:这种方法不行，我用对照表的方式已经弄出来了，但是觉得太笨拙了，有没有直接就把unicode字符转为iso-8859-1的方法
网友回复: {unescape}
输出编码：utf-8。
(加号) 解析为空格。
%?? 解析为单字节字符。
%u???? 解析为 unicode 字符。

}
echo unescape('this is %u9996%u9875. '); // prints "this is 主页. ".
