# Created by cloud-init v. 0.7.7 on Wed, 29 Jun :51 +0000
LANG=&en_US.UTF-8&因此，在R中，我们可以这样做：readRenviron(&/etc/default/locale&)
LANG &- Sys.getenv(&LANG&)
if(nchar(LANG))
Sys.setlocale(&LC_ALL&, LANG)Apache还在/etc/apache2/envvars可以取消注释以启用此操作。我想你需要检查一下操作系统。区域设置名称因操作系统而异，请参阅帮助文件中的示例。?Sys.getlocale()

你好，游客
Ubuntu修改locale问题解决
来源：Linux社区&
作者：dgd2010
本文针对的问题是& 安装中文语言包&&Ubuntu Server中文问题&，&Ubuntu更改语言环境&，&Ubuntu locale的设定&，&cannot change locale (zh_CN.UTF-8)&，&Linux中文乱码&，&Linux字符集的修改&，&Linux乱码的解决办法&等问题，提供一站式解决。如果系统显示中文异常，例如出现显示中文乱码等，可以参考本文章。关于系统的修改办法，请参考文章末尾的描述。
终端显示中文正常，应用程序里面显示中文异常。
$&sudo&dpkg-reconfigure&locales
perl: warning: Setting locale failed. & & perl: warning: Please check that your locale settings: & & & & LANGUAGE = "zh_CN:zh:en_US:en", & & & & LC_ALL = "zh_CN.UTF-8", & & & & LANG = "zh_CN.UTF-8" & & & & are supported and installed on your system. & & perl: warning: Falling back to the standard locale ("C"). & & locale: Cannot set LC_CTYPE to default locale: No such file or directory & & locale: Cannot set LC_MESSAGES to default locale: No such file or directory & & locale: Cannot set LC_ALL to default locale: No such file or directory & & /bin/bash: warning: setlocale: LC_ALL: cannot change locale (zh_CN.UTF-8) & & Generating locales... & & & en_US.UTF-8... /usr/sbin/locale-gen: line 177: warning: setlocale: LC_ALL: cannot change locale (zh_CN.UTF-8) & & up-to-date & & Generation complete.
$&man&locale

locale: Cannot set LC_CTYPE to default locale: No such file or directory & & locale: Cannot set LC_MESSAGES to default locale: No such file or directory & & locale: Cannot set LC_ALL to default locale: No such file or directory & & LANG=zh_CN.UTF-8 & & LANGUAGE=zh_CN:zh:en_US:en & & LC_CTYPE="zh_CN.UTF-8" & & LC_NUMERIC="zh_CN.UTF-8" & & LC_TIME="zh_CN.UTF-8" & & LC_COLLATE="zh_CN.UTF-8" & & LC_MONETARY="zh_CN.UTF-8" & & LC_MESSAGES="zh_CN.UTF-8" & & LC_PAPER="zh_CN.UTF-8" & & LC_NAME="zh_CN.UTF-8" & & LC_ADDRESS="zh_CN.UTF-8" & & LC_TELEPHONE="zh_CN.UTF-8" & & LC_MEASUREMENT="zh_CN.UTF-8" & & LC_IDENTIFICATION="zh_CN.UTF-8" & & LC_ALL=
$&localectl&list-locales
C.UTF-8 & & en_US.utf8 & & zh_CN.utf8
问题解决办法
要想达到应用程序中正常显示中文字符的目的，要下面的三个变量应该如下，
LANG=zh_CN.UTF-8& &
LANGUAGE=zh_CN:zh:en_US:en& &
LC_ALL=LC_ALL=zh_CN.UTF-8
但问题在于&LC_ALL to default locale: No such file or directory&和&LC_ALL: cannot change locale (zh_CN.UTF-8) &，因此重新安装中文语言包。
执行下面命令
sudo&apt-get&-y&install&language-pack-zh-hans
sudo&apt-get&-y&install&language-pack-zh-hans&language-pack-zh-hans-base
如果想支持繁体字，则执行
sudo&apt-get&-y&install&language-pack-zh-hant
sudo&apt-get&-y&install&language-pack-zh-hant&language-pack-zh-hant-base
再执行locale命令设置当前locale环境
相关的文件和参考
相关手册：man locale(1), locale(5), locale(7)
相关文件：/usr/share/i18n/SUPPORTED
相关命令：
locale --all-locales 列出当前系统中所有支持的locale
localectl list-locales 列出当前系统中所有可用的locale
localectl set-locales LOCALE... 修改当前系统中的locale，与locale功能相同，与export上文提到的三个变量相同
对于CentOS，可以直接编辑/etc/sysconfig/i18n文件，将LANG="en_US.UTF-8"设置成LANG="zh_CN.UTF-8"，除此之外，CentOS下locale命令的显示结果如下：
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_MESSAGES="en_US.UTF-8" & &LC_PAPER="en_US.UTF-8" & &LC_NAME="en_US.UTF-8" & &LC_ADDRESS="en_US.UTF-8" & &LC_TELEPHONE="en_US.UTF-8" & &LC_MEASUREMENT="en_US.UTF-8" & &LC_IDENTIFICATION="en_US.UTF-8" & &LC_ALL=
其中，LC_ALL=为空，但并不是表示这里不对，而是LC_ALL=实际上等于LC_COLLATE、LC_CTYPE、LC_MONETARY、LC_MESSAGES、LC_NUMERIC、LC_TIME，参见locale(7)。

unicode编码UTF-8和locale概念

关注作者，不错过每一篇精彩en_US.UTF-8和zh_CN.UTF-8之间是什么区别？ - ITeye问答
最近装linux系统，有时会出乱码，有人建议和编码方式有关。
网上查了下，还是有点搞不清en_US.UTF-8和zh_CN.UTF-8两者到底在什么地方有差别，希望能给予指点。
顺便，还有哪些资料可以看下？
问题补充：参考资料：http://en.wikipedia.org/wiki/UTF-8
问题补充：谢谢blogzhoubo的回复。不过在我的arch系统上，有这么个情况，当我把LANG的的值设为zh_CN.UTF-8时，系统软件pacman以及自带的编辑软件nano上能正常显示的英文变成了乱码，这是什么原因？
乱码图片见 http://i.imgur.com/ywoYR.jpg
问题补充：archlinux的版本是archlinux--dual.iso，从emule上下载的，看着不太像是汉化的。
除了汉化之外，会不会有其它可能的原因？
en_US.UTF-8：你说英语，你在美国，字符集是utf-8
zh_CN.UTF-8：你说中文，你在中国，字符集是utf-8
如果你的LANG环境变量是en_US.UTF-8，那么系统的菜单、程序的工具栏语言、输入法默认语言就都是英文的。
如果你的LANG环境变量是zh_CN.UTF-8，那么系统的菜单、程序的工具栏语言、输入法默认语言就都是中文的。
在显示字符时，en_US.UTF-8和zh_CN.UTF-8会在不同的目录寻找一个叫LC_IDENTIFICATION的文件。如果找不到，要显示的字符又不是ASCII，会出现乱码。贴一下自己遇到的问题吧。注意两次write()系统调用。
