带有 utf-8 的 Java BufferedWriter 对象 [英] Java BufferedWriter object with utf-8

问题描述

我有以下代码，我想让输出流使用 utf-8.基本上我有像 é 这样的字符，它们显示为 é 所以它看起来像是一个编码问题.

I have the following code and I want to make the outputstream use utf-8. Basically I have characters like é that appear as é so it looks like an encoding issue.

我见过很多使用...的例子

I've seen lots of examples that use...

OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(path),"UTF-8");

我目前的代码是...

BufferedWriter out = new 
BufferedWriter(new FileWriter(DatabaseProps.fileLocation + "Output.xml"));

是否可以在不使用 OutputStreamWriter 的情况下将该对象定义为 UTF-8?

Is it possible to define this object as UTF-8 without having to use the OutputStreamWriter?

谢谢，

推荐答案

没有.FileWriter 不允许您指定编码，这非常烦人.它始终使用系统默认编码.只需吸收它并使用 OutputStreamWriter 包装一个 FileOutputStream.当然，您仍然可以将 OutputStreamWriter 包装在 BufferedWriter 中:

No. FileWriter doesn't let you specify the encoding, which is extremely annoying. It always uses the system default encoding. Just suck it up and use OutputStreamWriter wrapping a FileOutputStream. You can still wrap the OutputStreamWriter in a BufferedWriter of course:

BufferedWriter out = new BufferedWriter
    (new OutputStreamWriter(new FileOutputStream(path), StandardCharsets.UTF_8));

或者从 Java 8 开始:

Or as of Java 8:

BufferedWriter out = Files.newBufferedWriter(Paths.of(path));

(当然，您可以将系统默认编码更改为 UTF-8，但这似乎有点极端.)

(Of course you could change your system default encoding to UTF-8, but that seems a bit of an extreme measure.)
