Java-é成为é©-如何修复 [英] Java - é becomes é - How to fix it

问题描述

我有一个法语的文件夹树。在阅读文件夹/文件时，它返回é而不是é。我替换了字符，但这不是一个好的解决方案。我怎样才能解决这个问题 ？
我在Google上找到了一些答案，但这对我没有帮助。

I have a folder tree in French. While I'm reading it's folders/files, it returns é instead of é. I replace the character, but it is not a good solution. How can I fix this ? I found some answers on google, but it doesn't help me.

谢谢！

推荐答案

启动应用程序时，将编码设置为utf-8 ：

java -Dfile.encoding="UTF-8" YourMainClass

请注意，如在上面的链接中，许多Java类都缓存编码；因此，如果您在运行时更改编码，则可能不会影响我们所关注的所有类。

Note that as mentioned in the link above, many Java classes cache the encoding; therefore if you change the encoding during run-time, it may not affect all of the classes that we are concerned.

从他对的回答中的/stackoverflow.com/users/471272/tchrist\">tchrist https://stackoverflow.com/questions/5688728/php-to-rtf-e-becomes-a>另一个问题：

Copying explanation from tchrist in his answer to another question:

A \N {带小号的拉丁字母E} 字符是代码点 U + 00E9 。
在UTF-8中，即 \xC3\xA9 。

但是如果并将这两个字节视为不同的代码
指向 U + 00C3 和 U + 00A9 \N {带
波浪符号的拉丁文大写字母A} 和 \N {COPYRIGHT SIGN} ，

But if you turn around and treat those two bytes as distinct code points U+00C3 and U+00A9, those are \N{LATIN CAPITAL LETTER A WITH TILDE} and \N{COPYRIGHT SIGN}, respectively.
