Hi,
In various places of the BBDB source code, it uses (downcase name) like
tricks to compare the identifiers, e.g. aka names. But default downcase
function of emacs uses current LC_CTYPE that emacs session is
initialized with. As a result of this, when gnus receives messages
encoded in different locales, bbdb doesn't switch to the case conversion
table related mail locale is set to and `downcase' doesn't work as it
should. Consider below case.
- Emacs is initialized with en_US.UTF-8 locale,
- And mail is encoded in tr_TR.UTF-8 where "From:" line is "İI".
By default, (downcase name) will return "İi", which is obviously
broken. (The correct conversion should be "iı".)
I searched previous posts[1] regarding with the similar issues, which
recommends (funcall 'string-make-unibyte name) like hacks, but this
doesn't solve the problem too. (Locale is still not changed during
conversion.)
(let ((name (string-make-unibyte "İI")))
(list name (downcase name)))
=> ("\320I" "\320i")
I'm not very good at BBDB internals. Could somebody help me to fix the
problem?
Regards.
