Yandex BODYSTRUCTURE CHARSET “X-UNKNOWN”
Yandex does not recognize UTF-8 charset correctly. For a message with text part using utf-8 charset:
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit
Yandex returns “X-UNKNOWN” as CHARSET instead of correct utf-8 in BODYSTRUCTURE response:
C: 11b7e19c9cd84f0f UID FETCH 1 (UID BODYSTRUCTURE)
S: * 1 FETCH (UID 1 BODYSTRUCTURE (“TEXT” “PLAIN” (CHARSET “X-UNKNOWN”) NIL NIL NIL 11894 0 NIL NIL NIL NIL))
