公安备案印章查询:关于网页不正常显示汉字的问题。谢谢大家！

我前几天在网上找了一个外国的模板，但是当我修改完源文件的时候刷新看了一下。主页居然不显示汉字。全是显示°¡Å¶这样的文字。请教高手如何可以将其改为汉字。
原〈HEAD〉〈/HEAD〉的代码如下：
<TITLE>asdfff</TITLE>
<META content="Cutepage 2.0" name=GENERATOR>
<META content="text/html; charset=iso-8859-1" http-equiv=Content-Type>
<STYLE type=text/css>

<!--

body { font-family:"Verdana", "Arial", "Helvetica", "sans-serif"; font-size: 9pt}

p { font-family:"Verdana", "Arial", "Helvetica", "sans-serif"; font-size: 9pt}

a:link { color: #0000FF; text-decoration: none}

a:visited { text-decoration: none}

a:hover { color: #FF0033; text-decoration: underline}

td { font-family: "Verdana", "Arial", "Helvetica", "sans-serif"; font-size: 9pt}
.CompanyName {font-family: "Verdana", "Arial", "Helvetica", "sans-serif"; font-size: 20pt}
-->

</STYLE>
<SCRIPT language=javascript>
<!--
function img_act(imgName) {
if(browser){
imgOn = eval(imgName+"on.src");
document[imgName].src = imgOn;
}
}

function img_inact(imgName)
{
if(browser){
imgOff = eval(imgName+"off.src");
document[imgName].src = imgOff;
}
}
// -->
</SCRIPT>

<SCRIPT language=javascript>
<!--
var ns = false;
var browser = navigator.userAgent.substring(0,9);
if (browser == "Mozilla/3" || browser == "Mozilla/4") ns = true;

var dot_normal , dot_hot;
if (ns){
dot_normal = new Image (42,10);
dot_normal.src = "image/dot_off.gif";

dot_hot = new Image (42,10);
dot_hot.src = "image/dot_on.gif";
}

function switchimage (imagename, target)
{
if (ns) document.images[imagename].src = target.src;
}
// -->
</SCRIPT>

</HEAD>
上面就是代码。请教各位高手我应该如何修改才能让内容正常显示为汉字。谢谢。
