如何让记事本在没有 BOM 的情况下以 UTF-8 格式保存文本?

问题描述

我有一个带有特殊口音的

当我在Java中遇到这个问题时，我没有找到任何库来解析这前三个字节(BOM).所以我的建议:

• 使用PushbackInputStream(in, 3).
• 读取前三个字节
• 如果不是 BOM (EF BB BF)，则将它们推回
• 将流处理为 UTF-8

I have a CSV file with special accents and save it in Notepad by selecting UTF-8 encoding. When I read the file using Java, it reads the BOM characters too.

So I want to save this file in UTF-8 format without appending a BOM initially in Notepad.

Otherwise, is there a built-in class in Java that eliminates the BOM characters that present at beginning, when reading the contents in a file?

解决方案

1. Use Notepad++ - it is free and much better than Notepad. It will help to save text without a BOM using Encoding → Encode in UTF-8 without BOM:
   
   Notepad++ v6 and olders:
   
   Notepad++ v7+:
   

2. When I encountered this problem in Java, I didn't find any library to parse these first three bytes (BOM). So my advice:

   • Use PushbackInputStream(in, 3).
   • Read the first three bytes
   • If it's not BOM (EF BB BF), push them back
   • Process the stream as UTF-8
