Steps to reproduce

If you download a file that contains character like éöàäèü the browser prompt the wrong filename like =utf-8_B_dGVzdCBjb24gc3BhemkgZSDDpMOgw6nDti50eHQ==.txt
The problem is reproducible if you download file using a webapi if I set the filename:

response.Content.Headers.ContentType = new MediaTypeHeaderValue(“application/octet-stream”);
response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue(“attachment”);
response.Content.Headers.ContentDisposition.FileName = "test éöàäèü.pdf";

the webapi encode the filename using RFC6266 and in chrome and firefox work well but with edge and ie11 does not work.
