RHEL6 telnet终端中文显示乱码解决办法   ##备份配置文件 cp  /etc/sysconfig/i18n  /etc/sysconfig/i18n.bak   ##修改配置文件 vi /etc/sysconfig/i18n ##将内容改为 LANG="zh_CN.GB18030" LANGUAGE="zh_CN.GB18030:zh_CN.GB2312:zh_CN" SUPPORTED="zh_CN.GB18030:zh_CN:zh:en_US.UTF-8:en_US:en" SYSFONT="lat0-sun16"   i18n是 internationalization 的缩写形式，意即在 i 和 n 之间有 18 个字母，本意是指软件的“国际化”. i18n支持多种语言，不过同一时间只能是英文和一种选定的语言，例如英文+中文、英文+德文、英文+韩文等等；   /etc/sysconfig/i18n Controls the system font settings. The language variables are used in /etc/profile.d/lang.sh. An example i18n file:   LANG="en_US" LC_ALL="en_US" LINGUAS="en_US"   Options:   * LANG= set locale for all categories, can be any two letter ISO language code. * LC_CTYPE= localedata configuration for classification and conversion of characters. * LC_COLLATE= localedata configuration for collation (sort order) of strings. * LC_MESSAGES= localedata configuration for translation of yes and no messages. * LC_NUMERIC= localedata configuration for non-monetary numeric data. * LC_MONETARY= localedata configuration for monetary data. * LC_TIME= localedata configuration for date and time. * LC_ALL= localedata configuration overriding all of the above. * LANGUAGE= can be a : separated list of ISO language codes. * LINGUAS= can be a ' ' separated list of ISO language codes. * SYSFONT= any font that is legal when used as /usr/bin/consolechars -f $SYSFONT ... (See console-tools package for consolechars command) * UNIMAP= any SFM (screen font map, formerly called Unicode mapping table - see consolechars(8))   /usr/bin/consolechars -f $SYSFONT --sfm $UNIMAP * SYSFONTACM= any ACM (application charset map - see consolechars(8))   /usr/bin/consolechars -f $SYSFONT --acm $SYSFONTACM   The above is used by the /sbin/setsysfont command (which is run by rc.sysinit at boot time.)
