There does seem to be a bug regarding search in unibyte buffers,
;; This works
(let ((case-fold-search nil)) (search-forward "\377"))
;; This actually matches \277 instead!
(let ((case-fold-search t)) (search-forward "\377"))
Isearch works, by luck, since it binds case-fold-search to nil because
of this strange behavior of `downcase' in a unibyte context,
(let ((default-enable-multibyte-characters nil))
(with-temp-buffer
(downcase 255))) ; worked correctly in Emacs 22
