response.go:669–690

HasContentType succeeds if response contains Content-Type header with given media type and charset. If charset is omitted, and mediaType is non-empty, Content-Type header should contain empty or utf-8 charset. If charset is omitted, and mediaType is also empty, Content-Type header should contain n

// should contain no charset.
