I agree.  My mailer does, but the code for UTF-8 in the From and Subject fields appears to be 
some kind of html code.

Whenever there are non-ascii characters in the subject/any other
header field, it is mime-encoded. (examples)
MIME (Multipurpose Internet Mail Extensions) Part Three:
              Message Header Extensions for Non-ASCII Text
The following are examples of message headers containing 'encoded-

   From: =?US-ASCII?Q?Keith_Moore?= <>
   To: =?ISO-8859-1?Q?Keld_J=F8rn_Simonsen?= <>
   CC: =?ISO-8859-1?Q?Andr=E9?= Pirard <>
   Subject: =?ISO-8859-1?B?SWYgeW91IGNhbiByZWFkIHRoaXMgeW8=?=
all valid, although the From one is unnecessary. both quoted printable
as well as base64 variants are shown, examples with different charsets
are shown (although it is not common to use different encodings, and
even less common to mix them in one single header field)

I never saw html in from and/or subject lines ever, not in spam, not
in other posts.

 Otherwise the UTF-8 coding appears somewhere in the header, I believe.  And I've never seen the 
string I quoted anywhere other than in these two fields.

You did not quote any string. you did say it starts with "=utf-8?"
(and probably missed a ? here), but didn't quote the string. A charset
definition is not spam nor html.

And while it is true that most spam has this trait (as most spam that
passes the filters is from china or russia and hence need to encode
the text), the opposite conclusion (everything that has encoded
characters is spam) is wrong.
