Exporting Euro symbol in excel from asp.net.

I was working with exporting GridView to Excel. GridView contains one column that has currency symbols. After exporting to excel all currency were displaying correctly but Euro(€) symbols got converted to something other characters like this "€" . After searching on internet i got solution. below is the solution.


public void ExportExcel(string filename, GridView gv)
{
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=" + filename + ".xls");
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
string output = sw.ToString();
//////////////////////
byte[] euroByte = new byte[1];
euroByte[0] = (byte)128;
bool isAfterFirst = false;
foreach (string item in output.Split('€'))
{
if (isAfterFirst)
{
Response.OutputStream.Write(euroByte, 0, 1);
}
Response.Write(item);
Response.Flush();
isAfterFirst = true;
}
Response.Write("\r\n");
//////////////////////
Response.End();
}
