かな漢字日本語なvalue値入りのcookieをjavascriptでもperlでも

perlでcookieを入れて

	my $c_name    = new CGI::Cookie(-name    =>  'yourNAME',
	                        -value   =>  '山田太郎',
	                        -expires =>  $EXPIRETIME
	                    );

javascriptでそいつを取り出す

function ReadCookie(key) {
	var sCookie = document.cookie;
	var aData = sCookie.split(";");
	var oExp = new RegExp(" ", "g");
	key = key.replace(oExp, "");
	var i = 0;
	while (aData[i]) {
		var aWord = aData[i].split("=");
		aWord[0] = aWord[0].replace(oExp, "");
		if (key == aWord[0]) return aWord[1];
		if (++i >= aData.length) break;
	}
	return "";
}
document.write(decodeURIComponent(ReadCookie("myNAME")));

要はdecodeURIComponent

decodeURIではなくて、decodeURIComponent
