有些关于编码的问题，是不是因为系统支持的语言或者编码问题，
使用locale查看目前的支持语言：
# locale
LANG=zh_CN.GB18030
LC_CTYPE="zh_CN.GB18030"
LC_NUMERIC="zh_CN.GB18030"
LC_TIME="zh_CN.GB18030"
LC_COLLATE="zh_CN.GB18030"
LC_MONETARY="zh_CN.GB18030"
LC_MESSAGES="zh_CN.GB18030"
LC_PAPER="zh_CN.GB18030"
LC_NAME="zh_CN.GB18030"
LC_ADDRESS="zh_CN.GB18030"
LC_TELEPHONE="zh_CN.GB18030"
LC_MEASUREMENT="zh_CN.GB18030"
LC_IDENTIFICATION="zh_CN.GB18030"
LC_ALL=

# vi /etc/sysconfig/i18n
LANG="zh_CN.GB1803dd0"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"

中文编码

其他服务器的编码状态
# vi /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"

# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"

将lost的这台服务器修改下编码为en_US.UTF-8
#LANG="en_US.UTF-8"

#vi /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"

终于恢复正常了。
