I'm exporting a table of data to csv format, eg
"COL1","COL2","COL3"
"1","some text", "£232.00"
"2","some more text", "£111.00"
"3","other text", "£2.00"
The code to export is fairly simple using an ashx handler
context.Response.Clear()
context.Response.ContentType = "text/csv"
context.Response.AddHeader("Content-disposition", "attachment;filename=data.csv")
context.Response.AddHeader("Cache-Control", "must-revalidate")
context.Response.AddHeader("Pragma", "must-revalidate")
context.Response.Write(data)
context.Response.Flush()
context.Response.End()
My issue is when excel trys to open the exported file the character  appears before all £ signs, eg £232.00 when the value should be £232.00
