Hello,

please press C-d on this message, you'll see the attached
email; it's subject contains "йМХЦЮ  йНРЕКЭМХЙНБЮ Х вЕАНРЮЕБЮ".
The subject is encoded as koi8-r, while the correct
charset is windows-1251 (it was an error of user's mail agent).

when i want to see the correctly encoded subject in gnus, i press
  0 g windows-1251 RET
and gnus re-encodes the message (both headers and body) in
windows-1251 encoding.

for this, you need to execute
(codepage-setup 1251)
(define-coding-system-alias 'windows-1251 'cp1251)

now, the bug in gnus is this:

  after doing such reencoding with 0 g windows-1251 RET,
  i see correctly re-encoded subject in the Article buffer:
  Subject: Книга  Котельникова и Чеботаева
  but in the Summary buffer, i see only "Книга"
  but the rest of the subject is not shown.

That may be due to the fact that in the original message the subject
consists of several lines:

Subject: =?KOI8-R?Q?=CA=ED=E8=E3=E0?=
 =?KOI8-R?Q?__=CA=EE=F2=E5=EB=FC=ED=E8=EA=EE=E2=E0_=E8?=
 =?KOI8-R?Q?_=D7=E5=E1=EE=F2=E0=E5=E2=E0?=

and the word "Книга" is on the first line; and gnus incorrectly fails
to show the rest of the re-encoded subject in the Summary buffer.
(without re-encoding, it shows the whole subject).

Best,
v.
