I explain about this patch.
0) bash invokes with system locale setting configured in /etc/environment
or C locale(from login, sshd or others).
1) eval ~/.bashrc and others.
if there are locale setting, such as LANG=ll_CC, it will call
setlocale(LC_ALL, value); in bash/locale.c:set_lang()
2) after startup script done, bash initializes terminal.
while terminal initialization, it checks current locale
in lib/readline/nls.c:_rl_init_eightbit().
However, it will call setlocale(LC_CTYPE, ""), so it will
*modify* locale category LC_CTYPE according to process environment.
Here, bash runs in LANG=C or something configured at starting up - 0).
Locale configuration in 1) doesn't change bash's environment, it only
call setlocale(LC_ALL, value) and set environment variables for bash's
child process.
So, readline consider that bash runs in C locale (configued in 0)),
so that it disable 8bit or multibyte features.
It can be solved with this patch. In lib/readline/nls.c:_rl_init_eightbit(),
it doesn't need to *modify* LC_CTYPE. What is required here is to *query*
locale category LC_CTYPE. So, it should use NULL for locale args for
setlocale() here.
