二维码解析后文字乱码

如图二维码
扫描后解析出来是乱码
urlencode后是如下内容
%C2%B0%C3%99%C2%B6%C3%88%C2%B0%C3%99%C2%BF%C3%86%C2%A3%C2%AD%C2%B6%C3%BE%C3%8E%C2%AC%C3%82%C3%AB%C2%B4%C3%8A%C3%8C%C3%B5
我用微信扫描解析却是可以的
内容是"百度百科－二维码词条"
这是经过了什么编码处理过么？怎么才能得到真正的结果？
------解决思路----------------------
这样判断能看明白吗

$s = '%C2%B0%C3%99%C2%B6%C3%88%C2%B0%C3%99%C2%BF%C3%86%C2%A3%C2%AD%C2%B6%C3%BE%C3%8E%C2%AC%C3%82%C3%AB%C2%B4%C3%8A%C3%8C%C3%B5';<br />$s = urldecode($s);<br /><br />if(mb_check_encoding('utf-8')) {<br />  $n = 0;<br />  for($i=0; $i<strlen($s); $i+=2) if((ord($s{$i}) & 0xf0) == 192) $n++;<br />  if($n > strlen($s)/2 * 0.8) $s = utf8_decode($s);<br />}<br />echo $s;

Copy after login
