开发语言：C#

IE8下载时木有问题的，就IE6会有这个情况。

下载代码片段：

var gb2312 = Encoding.GetEncoding("gb2312");
fileName = gb2312.GetString(Encoding.Convert(Encoding.Unicode, gb2312, Encoding.Unicode.GetBytes(fileName)));
Response.HeaderEncoding = Encoding.GetEncoding("gb2312");
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
Response.AddHeader("Content-Length", (dataToRead - p).ToString());
iStream.Position = p;
dataToRead = dataToRead - p;

IE6 下载文件时，下载对话框标题乱码
