Two things:
First, Ms Excel sucks. From that attached screenshot it's obvious that it
thought it was a space separated file. When actually using MS Office, I
recommend that you add `quoting=csv.QUOTE_ALL` to all csv writers.
Second, the HttpResponse object is file-like. You don't need to jump through
all the hoops. And MS Office is going to ignore your encoding anyway, so
there's no point in trying to fix it.
