C.UTF-8和en_US.UTF-8语言环境有什么区别？ [英] What is the difference between C.UTF-8 and en_US.UTF-8 locales?

问题描述

我正在将python应用程序从具有区域设置en_US.UTF-8的ubuntu服务器迁移到新的Debian服务器，该服务器默认已经设置了C.UTF-8。我试图了解是否会有影响，但无法在互联网上找到好的资源来了解两者之间的区别。

I'm migrating a python application from an ubuntu server with locale en_US.UTF-8 to a new debian server which comes with C.UTF-8 already set by default. I'm trying to understand if there would be any impact but couldn't find good resources on the internet to understand the difference between both.

推荐答案

通常 C 用于计算机， en_US 适用于说英语的美国用户（以及其他想要相同行为的人）。

In general C is for computer, en_US is for people in US who speak English (and other people who want the same behaviour).

计算机的 表示字符串有时会更加标准化（但仍使用英语），因此可以从其他程序读取程序的输出。使用 en_US ，可以改进字符串，可以改善字母顺序（也许是通过新的芝加哥风格规则等规则）。因此更加人性化，但可能不太稳定。注意：语言环境不仅用于字符串翻译，还用于排序规则（字母顺序，数字（例如千位分隔符），货币（我认为可以安全地预测$和2个十进制数字会保留），月份，星期几，等等。

The for computer means that the strings are sometime more standardized (but still in English), so an output of a program could be read from an other program. With en_US, strings could be improved, alphabetic order could be improved (maybe by new rules of Chicago rules of style, etc.). So more user-friendly, but possibly less stable. Note: locales are not just for translation of strings, but also for collation (alphabetic order, numbers (e.g. thousand separator), currency (I think it is safe to predict that $ and 2 decimal digits will remain), months, day of weeks, etc.

在您的情况下，这只是两个语言环境的UTF-8版本。

In your case, it is just the UTF-8 version of both locales.

一般情况下没关系，我通常更喜欢en_US.UTF-8，但通常没关系，在您的情况下（服务器应用程序），它只应更改日志和错误消息（如果使用 locale.setlocale（）。您应在应用程序内部处理客户端语言环境。从其他程序读取的程序应在打开管道之前设置 C ，因此

In general it should not matter. I usually prefer en_US.UTF-8, but usually it doesn't matter, and in your case (server app), it should only change log and error messages (if you use locale.setlocale(). You should handle client locales inside your app. Programs that read from other programs should set C before opening the pipe, so it should not really matter.

如您所见，可能没关系。您也可以使用 POSIX 语言环境，也在Debian中定义。您可以使用 locale -a 获得已安装语言环境的列表。

As you see, probably it doesn't matter. You may also use POSIX locale, also define in Debian. You get the list of installed locales with locale -a.

注意： -优化将规定 C / CU TF-8 区域设置：不翻译文件（ gettext ），并且使用简单的排序规则和数字格式规则，但这仅在服务器端可见

Note: Micro-optimization will prescribe C/C.UTF-8 locale: no translation of files (gettext), and simple rules on collation and number formatting, but this should visible only on server side.
