Subject: 23.0.50; utf7-decode failed with non latin-1 charactor
Date: Fri, 02 Nov 2007 02:45:35 +0900 [thread overview]
Message-ID: <87ir4lhnb4.wl%topia@clovery.jp> (raw)
I want to use imap's internationalized (japanese) folder name,
from Wanderlust. but I see error "Unable to convert from Unicode"
from utf7-u16-latin1-char-converter.
You can see with this code:
;; "Sent Mail" in Japanese, imap's UTF-7
(utf7-decode "&kAFP4W4IMH8w4TD8MOs-" 'imap)
tested on lisp/gnus/utf7.el:
;;; arch-tag: 96078b55-85c7-4161-aed2-932c24b282c7
so I found problem that utf7-utf-16-coding-system is nil, because:
* Emacs 23 has utf-16-be, but this coding system has BOM.
* utf-16-be-nosig is not found.
I found utf-16-be without BOM version, utf-16be. evalute above code
after (setq utf7-utf-16-coding-system 'utf-16be), no error occured.
Could you modify utf7-utf-16-coding-system to add utf-16be?
(defconst utf7-utf-16-coding-system
(cond ((mm-coding-system-p 'utf-16-be-no-signature) ; Mule-UCS
'utf-16-be-no-signature)
((and (mm-coding-system-p 'utf-16-be) ; Emacs 21.3, Emacs 22 (BOM?)
;; Avoid versions with BOM.
(= 2 (length (encode-coding-string "a" 'utf-16-be))))
'utf-16-be)
+ ((and (mm-coding-system-p 'utf-16be) ; Emacs 22 and later
+ ;; Avoid versions with BOM.
+ (= 2 (length (encode-coding-string "a" 'utf-16be))))
+ 'utf-16be)
((mm-coding-system-p 'utf-16-be-nosig) ; ?
'utf-16-be-nosig))
"Coding system which encodes big endian UTF-16 without a BOM signature.")
