Linux From Scratch 12.2/chapter09_locale — Chinese (Simplified Han script)
Some environment variables are necessary for native language support. Setting them properly results in:
下面将创建的 <filename>/etc/locale.conf</filename> 设定本地语言支持需要的若干环境变量，正确设定它们可以带来以下好处：

Replace <replaceable>&lt;ll&gt;</replaceable> below with the two-letter code for your desired language (e.g., <literal>en</literal>) and <replaceable>&lt;CC&gt;</replaceable> with the two-letter code for the appropriate country (e.g., <literal>GB</literal>). <replaceable>&lt;charmap&gt;</replaceable> should be replaced with the canonical charmap for your chosen locale. Optional modifiers such as <literal>@euro</literal> may also be present.
将下面的 <replaceable>&lt;ll&gt;</replaceable> 替换为所需语言的双字符代号 (例如<quote>en</quote>)，<replaceable>&lt;CC&gt;</replaceable> 替换为国家或地区的双字符代号 (例如<quote>GB</quote>)，<replaceable>&lt;charmap&gt;</replaceable> 替换为您选定的 locale 的标准字符映射。另外，还可以加入 <quote>@euro</quote> 等可选修饰符。

Charmaps can have a number of aliases, e.g., <literal>ISO-8859-1</literal> is also referred to as <literal>iso8859-1</literal> and <literal>iso88591</literal>. Some applications cannot handle the various synonyms correctly (e.g., require that <literal>UTF-8</literal> is written as <literal>UTF-8</literal>, not <literal>utf8</literal>), so it is the safest in most cases to choose the canonical name for a particular locale. To determine the canonical name, run the following command, where <replaceable>&lt;locale name&gt;</replaceable> is the output given by <command>locale -a</command> for your preferred locale (<literal>en_GB.iso88591</literal> in our example).
字符映射可能有多个别名，例如<quote>ISO-8859-1</quote>也可以称为<quote>iso8859-1</quote>或者<quote>iso88591</quote>。某些程序不能正确处理一些别名 (例如，<quote>UTF-8</quote>必须写作<quote>UTF-8</quote>才能识别，而不能识别<quote>utf8</quote>)，因此在多数情况下，为了保险起见，最好使用 locale 的规范名称。为了确定规范名称，执行以下命令，将 <replaceable>&lt;locale 名&gt;</replaceable> 替换成 <command>locale -a</command> 对于您希望的 locale 的输出 (以<quote>en_GB.iso88591</quote>为例)。

For the <literal>en_GB.iso88591</literal> locale, the above command will print:
对于<quote>en_GB.iso88591</quote>locale，以上命令输出：

This results in a final locale setting of <literal>en_GB.ISO-8859-1</literal>. It is important that the locale found using the heuristic above is tested prior to it being added to the Bash startup files:
这样就最终确定 locale 应设置为<quote>en_GB.ISO-8859-1</quote>。在将以上启发方法获得的 locale 添加到 Bash 启动文件之前，一定要进行下列测试：

Please note that the <command>localectl</command> command doesn't work in the chroot environment. It can only be used after the LFS system is booted with systemd.
请注意 <command>localectl</command> 只能在使用 systemd 引导的系统中使用。

The <literal>C</literal> (default) and <literal>en_US</literal> (the recommended one for United States English users) locales are different. <literal>C</literal> uses the US-ASCII 7-bit character set, and treats bytes with the high bit set as invalid characters. That's why, e.g., the <command>ls</command> command substitutes them with question marks in that locale. Also, an attempt to send mail with such characters from Mutt or Pine results in non-RFC-conforming messages being sent (the charset in the outgoing mail is indicated as <computeroutput>unknown 8-bit</computeroutput>). It's suggested that you use the <literal>C</literal> locale only if you are certain that you will never need 8-bit characters.
<quote>C</quote> (默认 locale) 和<quote>en_US</quote>(推荐美式英语用户使用的 locale) 是不同的。<quote>C</quote> locale 使用 US-ASCII 7 位字符集，并且将最高位为 1 的字节视为无效字符。因此，<command>ls</command> 等命令会将它们替换为问号。另外，如果试图用 Mutt 或 Pine 发送包含这些字符的邮件，会发出不符合 RFC 标准的消息 (发出邮件的字符集会被标为<quote>未知 8 位</quote>)。因此，您只能在确信自己永远不会使用 8 位字符时才能使用<quote>C</quote> locale。
