问个基础问题，locale ...

zh_CN.UTF-8和zh_CN.UTF8有区别吗？
今天发现控制台的locale(zh_CN.UTF8)和xterm(zh_CN.UTF-8)中的不一样，似乎是某次emerge world后的结果。。。

不明白，什么意思？
你把你执行过的命令和结果都贴出来

可能你其中一个写错了吧
zh_CN.UTF-8 should be correct

关键看你的/etc/locale.gen里怎么定义。zh_CN.UTF-8是通常的名称，其实你把它定义成zh_CN.UTF--8也是可以的。

# The format of each line:
# <locale> <charmap>

问题似乎不大。我觉得是不是bash的问题？还请各位指点一下gentoo都在具体哪几个文件来定义？以前用fc2时，记得是zh_CN.UTF-8:confused:

我觉得很奇怪
因为一般来说终端程序不会改变环境变量的设定
其实具体用UTF-8，还是UTF8，utf8都是一样的
在glibc内部，这个字符串会被normalize
http://www.gnu.org/software/libc ... tized-software.html
The only new thing is the normalized codeset entry. This is another goodie which is introduced to help reducing the chaos which derives from the inability of the people to standardize the names of character sets. Instead of ISO-8859-1 one can often see 8859-1, 88591, iso8859-1, or iso_8859-1. The normalized codeset value is generated from the user-provided character set name by applying the following rules:

   1. Remove all characters beside numbers and letters.
   2. Fold letters to lowercase.
   3. If the same only contains digits prepend the string "iso".

So all of the above name will be normalized to iso88591. This allows the program user much more freely choosing the locale name.
