Dockerfile编码是哪个？
Which is the Dockerfile encoding?
定义我的 Dockerfile 我到了这一行：
...
MAINTAINER Ramón <ramon@example.com>
...
我应该使用哪种编码来保存这个文件？
我应该转义非 ASCII 字符吗？
考虑到Docker is done in Go, and Go has native support for utf-8，最好保存一个直接用UTF-8编码的Dockerfile。
这样，所有 个字符（ASCII 或非 ASCII）都受支持。
参见“Dealing with encodings in Go”。
Even though Go has good support for UTF-8 (and minimal support for UTF-16), it has no built-in support for any other encoding.
If you have to use other encodings (e.g. when dealing with user input), you have to use third party packages, like for example go-charset.
这里Dockerfile最好直接UTF-8编码。
2016 年 7 月更新，docker 1.12-rc5 添加：
您需要正确设置语言环境，去掉重音，用基本的 docker run -it container env 检查编码，然后输入正确的编码，"Bible" 就是 http://jaredmarkell.com/docker-and-locales/
