javac和java的编码和语言环境错误
[英]javac and java are in wrong encoding and locale
问题描述
I'm on Windows 7. The system locale is zh_CN and there's no way to change the OS's locale. 
我在Windows 7上。系统区域设置为zh_CN，无法更改操作系统的区域设置。 When install java, it detected the system locale and therefore java and javac will, supposedly print its output in localized language (Chinese in this case). 安装java时，它会检测到系统区域设置，因此java和javac将以本地化语言（在这种情况下为中文）打印输出。 I don't want this behaviour but there's no way to change it. 我不希望这种行为，但是无法更改它。
However, it doesn't work. 但是，它不起作用。 I tried Cygwin, git bash and Win CMD, all print just question marks. 我尝试了Cygwin，git bash和Win CMD，所有这些仅打印问号。 See below sample output (from Cygwin): 请参见下面的示例输出（来自Cygwin）：
Anyone has any idea how to make it output English? 任何人都知道如何使其输出英语吗？ Any help is much appreciated! 任何帮助深表感谢！

I compared your and my output of javac and saw that in your case the text is much shorter. 我比较了您和我的javac输出，发现在您的情况下，文本要短得多。 So I believe that your javac prints messages in Chinese that is not supported by your terminal. 因此，我相信您的javac会以中文显示您的终端不支持的消息。 So, you should either teach your terminal Chinese or re-install JDK and choose English as a current interface language (if it is possible) or probably download English version of JDK. 因此，您应该教您的终端中文，或者重新安装JDK并选择英语作为当前的界面语言（如果可能），或者可能下载JDK的英语版本。
