从Java中的字符串中删除BOM [英] Remove BOM from string in Java

问题描述

我有一个文件的字符串，其中包含BOM（从UTF-8）。我想将此字符串转换为win-1251并将其放入文件中。

我以这种方式从字符串中删除BOM：

  out.write（l.replace（'\FEFF'，'\0'）+\\\
）; 
  

但它不工作。为什么？

在win-1251文件中输出此字符串：

 ？1，... SOME_TEXT_HERE 
  

首先？符号是非法的。

解决方案

您正在用U + 0000替换BOM，而不是空字符串。您应该用空字符串替换BOM，例如

  out.write（l.replace（\FFF， ）+\\\
）; 
  

I have string in file, that contains BOM (from UTF-8). I want to convert this string to win-1251 and put it in file.

I trying to remove BOM from string in this way:

out.write(l.replace('\uFEFF','\0') + "\n");

But it don't work. Why?

Output of this string in win-1251 file:

?1,...SOME_TEXT_HERE

First "?" sign is illegal.

解决方案

You're replacing the BOM with U+0000, rather than with an empty string. You should replace the BOM with the empty string, e.g.

out.write(l.replace("\uFEFF", "") + "\n");
