[fetch] "A value is a byte sequence that matches the field-content token production." (#213)

https://fetch.spec.whatwg.org/#concept-header-value

What about headers for which this is not true? It seems like browsers allow any byte sequence, as discussed in https://github.com/nodejs/http-parser/issues/281.

Fetch should probably be the spec that defines the error handling for "invalid" server responses.
