This is a unibyte buffer: "M-: enable-multibyte-characters RET"
reports nil.  So what you see are raw bytes of the encoded text.  You
need to decode it, e.g., by using decode-coding-region.  The header
says "Content-Type: text/html; charset=utf-8", so the coding-system to
use in decoding is utf-8.  For example:

  (decode-coding-region (point-min) (point-max) 'utf-8
                        (get-buffer-create "decoded"))
