在UCS-2中编写文本文件Little Endian，Java

问题描述

我正在尝试写入.txt文件，它必须是UCS-2 Little Endian，但是当我尝试

  writer = new PrintWriter（path，UTF-16LE）; 
  

从我读取的内容应该是一样的，但它不会在服务器上的特定应用程序中工作。当我在Notepad ++中打开工作（手动创建）的文件时，它表示它是UCS-2 Little Endian，但是当它像这样在Java中创建时，它表示UCS-2 LE w / o BO，服务器无法读取它。 / p>

我该怎么写才能工作？这是整个代码：

  writer = new PrintWriter（path，UTF-16LE）; （int j =（i  -  itemsInPlaylist + 1）; j  writer.println（listParsedFile.get（j）.getNameOfFile（））; 
 
} 
 itemsInPlaylist = 0; 
 writer.close（）; 
  

感谢任何建议。

解决方案

首先，您需要编写，以便您应用程序可以检测编码。 （不清楚你的意思是它说的 - 清楚的是，它是可以猜到它是UTF-16LE，但不如可靠的比你有BOM。）

所以只需添加：

  writer.write（\FEFF）; 
  

在您写任何其他内容之前。

I'm trying to write .txt file and it have to be UCS-2 Little Endian, but when I tried

writer = new PrintWriter(path, "UTF-16LE");

From what I read it should be the same, but it won't work in specific application on server. When I open file which works (created manually) in Notepad++ it says that it's "UCS-2 Little Endian" but when it's created in Java like this it says "UCS-2 LE w/o BO" and server cannot read it.

How could I write it so it will work? This is whole code:

writer = new PrintWriter(path, "UTF-16LE");
for (int j = (i - itemsInPlaylist + 1); j <= i; j++) {
    writer.println(listParsedFile.get(j).getNameOfFile());
}
itemsInPlaylist = 0;
writer.close();

Thanks for any suggestions.

解决方案

It sounds like you need to write a byte-order mark first, so that your application can detect the encoding. (It's not clear what you mean by "it says" - clearly whatever "it" is can guess that it's UTF-16LE, but less reliably than when you've got the BOM.)

So just add:

writer.write("\uFEFF");

before you write anything else.
