I have problem with redirect request when response header has non english
message. It shows me below stacktrace. I debug to HttpResponseEncoder.java line
47 and see it use us-ascii charset read header. So, when it read my response
header it throws exception because it can't read that message in ascii charset.
I temporary fixed by changed to UTF but is it have a reason or other ways to
change charset without change code or should it change to unicode.
