C# context.Response.OutputStream.Write Hebrew characters

Question

I'm trying to export a report to csv using this code:

byte[] csvBytes = AttachmentFileAgent.GetAttachmentFilesCSVBytes(context.Request["appCode"], performingPerson);
context.Response.AddHeader("content-disposition", "attachment; filename=ApplicationReport_" + context.Request["appCode"] + ".csv");
context.Response.ContentType = "text/csv;charset=utf-8";
context.Response.Charset = "utf-8";
context.Response.ContentEncoding = Encoding.UTF8;
context.Response.OutputStream.Write(csvBytes, 0, csvBytes.Length);

But the Hebrew content goes out in gibberish (׳›׳¢׳›׳’׳¢׳›׳’׳›׳¢). I tryied ising all kinds on encoding (UTF8, Unicode, ASCII) but nothing works...

Answer 1

Your changes to context.Response.ContentEncoding sets the encoding on the TextWriter used by context.Response.Output

When using context.Response.OutputStream you need to set the UTF-8 encoding used in your GetAttachmentFilesCSVBytesfunction.

Also see ASP.NET: Will Saving an XmlDocument to the Response.OutputStream honor the encoding?
