求asp程序，把汉字字符串转换为utf-8格式的字符串

[homoo]

比如语言的“语”字，他的gb2312格式下二进制编码为D3 EF,而utf-8格式下编码为E8 AF AD，这个时候我需要做的是把”语“字的编码从D3 EF更换到E8 AF AD，并且以字符串显示出来，那个ado.stream应该是可以做到的，可是我有个特殊环境无法调用ado.stream，现在求用程序把gb2312格式的”语“转换为utf-8格式的“语”

你没漏掉什么吧!

晕，怎么老贴这个代码啊
我现在已经能把代码
utf-8格式下编码为E8 AF AD
这个得到了，可是不知道怎么用utf-8的方式显示出来
chr只能是对2进制处理，我现在不会怎么把E8 AF AD转为utf-8格式对应的2进制代码，而不是gb2312对应的2进制代码

[homoo]

以上代码无效，我也是百度后才来问的

[btbtd]

楼主以这个方式思考一下
<% response.write chrW(45217):response.write ascW("好"):response.write chrW(22909) %>

[hurrayboy]

关注!

[rehearts]

以上他们提供的函数是对的，
当时你要输出这个值必须这样 response.BinaryWrite()
要获得这个值可以xmlhttp抓一下输出

有朋友说用utf-gb2312的对照表。
