nginx throws a 502 (invalid header) when downloading a file attachment if filename has a space character

[Kunal Pariani]

Never mind there's nothing wrong with nginx here.
It was one of the response headers sent by an upstream server (mainly
Content-Description:
2013923 10H56M56S633_PV.doc�) including this non-ascii char '?' which the
nginx didn't like and hence flagged it saying that it received an invalid
header.

Thanks
