One more data point: It only happens in Mails fetched via nnimap. If I
reproduce with nntp (that means if I send a news articles with 8bit
encoding and UTF-8) everything is displayed correctly. 

As stated in the bug report cited by Andreas above nnimap does have a function

(defsubst imap-disable-multibyte ()
  "Enable multibyte in the current buffer."
  (when (fboundp 'set-buffer-multibyte)
    (set-buffer-multibyte nil)))

which is called for every buffer involved (see e.g. imap-open). Might
this be the problem?

Have you ever considered how much text can fit in eighty columns?  Given that a
signature typically contains up to four lines of text, this space allows you to
attach a tremendous amount of valuable information to your messages.  Seize the
opportunity and don't waste your signature on bullshit that nobody cares about.
