Java源文件和失败测试的字符集 [英] Charset of Java source file and failing test
问题描述
首先，我想说我花了很多时间搜索解释/解决方案。我发现了这个问题的提示，但没有办法解决我的特定问题。因此，至少在某些情况下，一个主题的帖子似乎已被殴打死亡。
First, I'd like to say that I've spent a lot of time searching for an explanation/solution. I've found hints of the problem, but no way to resolve my particular issue. Hence the post on a topic that seems to have been beaten to death in at least some cases.
我有一个Java测试类，测试正确的编码/解码Mime实用程序。用于测试的字符串在源文件中声明，我们使用assertEquals（）在处理输入字符串后测试等式。这里是一个例子：
I have a Java test class that tests for proper encoding/decoding by a Mime utility. The strings used for testing are declared in the source file and we use assertEquals() to test equality after processing the input string. Here's an example:
String test = "S2, =?iso-8859-1?Q?F=E4ltstr=F6m?= =?iso-8859-1?Q?,_Patrik?= S3";
String expected = "S2, Fältström, PatrikS3";
在我的编辑器（以及其他外部编辑器，如Notepad ++和UltraEdit）中，输入字符串正确显示如果我选择读它为windows-1252或ISO-8859-1编码; UTF-8显示期望的字符串为F ltstr m。
In my editor (and other external editors such as Notepad++ and UltraEdit), the input strings are properly displayed if I choose to read it as windows-1252 or ISO-8859-1 encoding; UTF-8 displays the expected string as "F�ltstr�m".
在Windows 7机器上编译并运行时，我得到以下输出：
When compiled and run on a Windows 7 machine, I get the following output:
预期：S2，F ltstr m，PatrikS3
Expected :S2, F�ltstr�m, PatrikS3
实际：S2，Fältström，PatrikS3
Actual :S2, Fältström, PatrikS3
我在命令shell以及我的代码编辑器中得到了这个行为。奇怪的是，它在Windows XP机器上工作。但是我在命令shell中使用chcp检查了代码页，在这两种情况下，我得到相同的输出。我得到这个工作的唯一方法是使用-encoding windows-1252编译类，我不想因为各种原因。
I get this behaviour in a command shell as well as in my code editor. Bizarrely, it works on a Windows XP machine. Yet I checked the codepage using chcp in a command shell and I get the same output in both cases. The only way I got this to work is to compile the class using "-encoding windows-1252", which I don't want to be doing for a variety of reasons.
所以问题是：
1）XP和Windows 7之间有什么不同，使这失败？是否更改了默认平台编码？
2）我如何修复，以便它可以在Windows 7机器和Linux机器上工作？
So the questions are: 1) what's different between XP and Windows 7 that makes this fail? Has the default platform encoding changed? 2) how can I fix so that it will work both on a Windows 7 machine and a Linux machine?
非常感谢任何洞察力！ p>
Thanks a lot for any insight!
推荐答案
看起来你的Windows 7机器上使用的默认编码是UTF-8，而在Windows XP是Windows-1252。所以：在编译时始终是明确的，编译时使用，不依赖平台默认。
It looks like the default encoding used on your Windows 7 machine is UTF-8, while on Windows XP it is Windows-1252. So: always be explicit in the encoding your files use when compiling, don't depend on the platform default.
BTW：据我所知，在我的Windows 7机器仍然使用Windows-1252作为默认值。
BTW: As far as I know java on my Windows 7 machine still uses Windows-1252 as the default.
