近段时间在忙着把网站由原来的gb2312编码转换为utf-8编码，眼看快完成了，今天测试时却突然发现UBB代码转换出了问题，想请教各位达人帮忙解答解答

UBB代码在之前一直使用正常，在转换成utf-8编码后，所有图片和FLASH，只要是UBB代码中间包含了网址的全都不能正常显示
原本应该是“/”的转换后全都变成了“/]”
我的网站是ASP网站

例如：
UBB代码：
[IMG]http://www.[/IMG]

原gb2312编码下转换后为
<IMG src="http://www.
图片能正常显示

但转换为UTF-8编码后就变成了
<IMG src="http:/]/]www.]data/]attachment/]forum/]201108/]22/]003952l5b58n8gsn5iv52n.jpg">
无法显示图片

其他的FLASH等也是类似症状

请哪位高手帮忙解答一下啊
UBB源代码放在了附件里，也贴在二楼了，但是好像有些显示不正常
引用方式如<%= ubb2html(rs_detail_bg("bg_content"))%>

目前我只能勉强在最后面加一句
    ubb = Replace(ubb, "/]", "/", 1, -1, 1)
来缓解上面的错误，但又害怕会出现其他乱码
