即 %uXXXX 格式的，看着很不爽。iconv UNICODE 居然还不行，得是 UNICODEBIG

function fnJSUrlDecode($sOrg, $sCharset = "GBK") {
	$sPattern = "/%u[0-9a-f]{4}/i";
	preg_match_all($sPattern, $sOrg, $aOut);
	$aSearch = array();
	$aReplace = array();
	foreach ($aOut[0] as $sValue) {
		$aSearch[] = $sValue;
		$aReplace[] = iconv("UNICODEBIG", $sCharset, pack("H*", substr($sValue, 2)));
	}
	$sOut = str_replace($aSearch, $aReplace, $sOrg);
	return $sOut;
}

echo fnJSUrlDecode("word=%u6D4B%u8BD5%u6587%u5B57");
