    程序代码
<a href="#" onclick="window.open('http://www.webjx.com/test.aspx?title=网页教学网');">Links</a>

在test.aspx中只要获取title参数的值并显示出来即可本来用Request["title"]就可解决的问题却因链接所处页面的编码不同而变得复杂起来:

当链接所处的页面是用GB2312编码时,如果test.aspx也是GB2312则获取的参数值不乱码,否则乱码;
当链接所处的页面是用UTF-8编码时,如果test.aspx也是UTF-8则获取的参数值不乱码,否则乱码;

gb.htm:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>gb2312测试页</title>
</head>

<body>
<a href="#" onclick="window.open('http://www.webjx.com/test.aspx?title=网页教学网');">Links</a>
</body>
</html>

utf8.htm:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>utf-8测试页</title>
</head>

<body>
<a href="#" onclick="window.open('http://www.webjx.com/test.aspx?title=网页教学网');">Links</a>
</body>
</html>

test.aspx.cs:

private void Page_Load(object sender, System.EventArgs e)
{
    String Request1;
    Request1 = Request["title"];
    Response.Write(Request1);
}

有没办法让test.aspx不论URL中的参数以何种方式编码都能正常的获取显示呢?通过配置web.config的<globalization requestEncoding="gb2312|utf-8" />都只会顾此失彼,不能完美的解决我们的问题最终,在老农的提示下使用JS的escape问题得以完美解决:
gb.htm:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>gb2312测试页</title>
<script language="javascript">
function winopen(url,width,height)
{
    var newurl,arrurl;
    if(typeof(url) == "undefined" || url == "")
    {
        return ;
    }
    else
    {
        if(url.indexOf("?") == -1)
        {
            newurl = url;
        }
        else
        {
            newurl = url.substring(0,url.indexOf("?")+1);
            arrurl = url.substring(url.indexOf("?")+1).split("&");
            for(var i =0;i<arrurl.length;i++)
            {
                newurl += arrurl[i].split("=")[0] + "=" + escape(arrurl[i].split("=")[1]) + "&";
            }
            newurl = newurl.substring(0,newurl.length-1);
        }
    }
    if(typeof(width) != "number" || typeof(height) != "number")
    {
        window.open(newurl);
    }
    else
    {
        window.open(newurl,"","width=" + width + ",height=" + height);
    }
}
</script>
</head>

<body>
<a href="#" onclick="winopen('http://www.webjx.com/test.aspx?title=网页教学网');">Links</a>
</body>
</html>

utf8.htm:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>utf-8测试页</title>
<script language="javascript">
function winopen(url,width,height)
{
    var newurl,arrurl;
    if(typeof(url) == "undefined" || url == "")
    {
        return ;
    }
    else
    {
        if(url.indexOf("?") == -1)
        {
            newurl = url;
        }
        else
        {
            newurl = url.substring(0,url.indexOf("?")+1);
            arrurl = url.substring(url.indexOf("?")+1).split("&");
            for(var i =0;i<arrurl.length;i++)
            {
                newurl += arrurl[i].split("=")[0] + "=" + escape(arrurl[i].split("=")[1]) + "&";
            }
            newurl = newurl.substring(0,newurl.length-1);
        }
    }
    if(typeof(width) != "number" || typeof(height) != "number")
    {
        window.open(newurl);
    }
    else
    {
        window.open(newurl,"","width=" + width + ",height=" + height);
    }
}
</script>
</head>

<body>
<a href="#" onclick="winopen('http://www.webjx.com/test.aspx?title=网页教学网',300,400);">Links</a>
</body>
</html>

现在完全不用考虑链接所在页面的编码方式,也不用绞尽脑汁去想如何在test.aspx对不同编码的参数值进行转换,只需用一个escape就够了,very good!
