24.0.50; Searching in binary buffers |

Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux) |
search-forward seems to work strangely in binary/unibyte buffers.
Create a file test.el containing this code:
(defvar test-string (unibyte-string #xce))
(with-temp-file "test.txt"
(set-buffer-multibyte nil)
(setq buffer-file-coding-system 'binary)
(insert test-string))
(with-current-buffer (get-buffer-create "test.txt")
(set-buffer-multibyte nil)
(setq buffer-file-coding-system 'binary)
(erase-buffer)
(insert-file-contents "test.txt")
(search-forward test-string))
Executing this with: emacs -Q -batch -l test.el
prints:
Search failed: "Î"
[Exit 255]
The Lisp code creates a file test.txt for a single character ?\xce. As
expected, hexdump -C test.txt prints:
00000000 ce |Î|
00000001
Opening and searching that character with Emacs fails. That's
definitely not what I was expecting. What's the proper way to search
those characters?
