    Research direction

    Start by reading the attached header-decoding.patch and the superseding bpo-22233 issue. Then trace the relevant http.client header parsing behavior and check whether the UTF-8 truncation is addressed there; done means confirming the resolution in the superseding issue rather than starting duplicate work.
