<br />
function unescape($str) {<br />
  $str = rawurldecode($str);<br />
  preg_match_all("/(?:%u.{4})<br><font color='#FF8000'>------解决方案--------------------</font><br>&#x.{4};<br><font color='#FF8000'>------解决方案--------------------</font><br>&#\d+;<br><font color='#FF8000'>------解决方案--------------------</font><br>.+/U",$str,$r);<br />
  $ar = $r[0];<br />
print_r($ar);<br />
  foreach($ar as $k=>$v) {<br />
    if(substr($v,0,2) == "%u")<br />
      $ar[$k] = iconv("UCS-2","GB2312",pack("H4",substr($v,-4)));<br />
    elseif(substr($v,0,3) == "&#x")<br />
      $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));<br />
    elseif(substr($v,0,2) == "&#") {<br />
echo substr($v,2,-1)."<br>";<br />
      $ar[$k] = iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));<br />
    }<br />
  }<br />
  return join("",$ar);<br />
}<br />

有一种方法，直接用JS好了，如

<br />
<script language="javascript"><br />
code=26053;<br />
str = String.fromCharCode(code);<br />
document.write(str);<br />
</script><br />
