broken by #314. This is compatible with the fix introduced in #314.
To use non-ASCII text/filename in clipboard, chansrv needs to be run
with LC_CTYPE=*.UTF-8 because the behaviour of mbstowcs(3) function
called in chansrv depends on LC_CTYPE[1]. However #314 made
LC_CTYPE=C in chansrv context. Even if LANG and LC_* are set in
.bashrc, /etc/profile, /etc/locale.conf or something like that,
it doesn't affect in chansrv context because chansrv doesn't source
any of them unlike sesman.
So do not set LC_CTYPE to blank or "C" in g_init() in order to get
g_mbstowcs and g_wcstombs to work properly with non-ASCII UTF-8
characters in any context.
Setting LC_CTYPE to *.UTF-8 doesn't obstruct applying system
language in RHEL [2].
[1] Linux man page says:
The behavior of mbstowcs() depends on the LC_CTYPE category of
the current locale.
