Encoding issues in Azure WebApps - azure

Question

I'm trying to download an Excel file from my web page. In the local environment, everything works fine. But in Azure the encoding of the file name gets screwed up. I have already set the globalization tag in web.config as follows:
<globalization fileEncoding="utf-8" requestEncoding="utf-8" responseEncoding="utf-8"/>
Here is how the response is built:
string name = v_NomeArquivo + ".xlsx";
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Buffer = true;
Response.ContentType = "application/ms-excel";
Response.AddHeader("content-disposition", "attachment; filename=" + name);
Response.BinaryWrite(v_ExcelPackage.GetAsByteArray());
Response.End();
The headers on Azure:
cache-control: private
content-disposition: attachment; filename=Relatório Contrato Limpeza e Higinenização - 2020-10-06_10-55-26.xlsx
content-type: application/ms-excel
date: Tue, 06 Oct 2020 13:55:26 GMT
server: Microsoft-IIS/10.0
status: 200
x-aspnet-version: 4.0.30319
x-powered-by: ASP.NET
And on local:
Cache-Control: private
content-disposition: attachment; filename=Relatório Contrato Limpeza e Higinenização - 2020-10-06_10-58-59.xlsx
Content-Type: application/ms-excel
Date: Tue, 06 Oct 2020 13:58:59 GMT
Server: Microsoft-IIS/10.0
Transfer-Encoding: chunked
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET
The only difference is the filename getting messed up and the Transfer-Encoding, could it be it?

Answer 1

You need to use System.Web.HttpUtility.UrlEncode method.
Ex:
string name = System.Web.HttpUtility.UrlEncode(v_NomeArquivo + ".xlsx", System.Text.Encoding.UTF8);
