Subject: bug#5799: 24.0.50; Case and search problems in unibyte buffers
Date: Mon, 29 Mar 2010 22:48:08 +0200 [thread overview]
Message-ID: <87bpe6g8hj.fsf@gnu.org> (raw)
http://lists.gnu.org/archive/html/help-gnu-emacs/2010-03/msg00246.html
This correctly finds a \377 character in a unibyte buffer:
(let ((case-fold-search nil)) (search-forward "\377"))
This fails to match \377 and actually finds \277 instead:
(let ((case-fold-search t)) (search-forward "\377"))
`downcase' behaves strangely too:
(let ((default-enable-multibyte-characters nil))
(with-temp-buffer
(downcase 255)))
=> 4194303
These problems exist in trunk and Emacs 23, and did not occur in
Emacs 22.
