如何制作记事本以在没有BOM的情况下将文本保存为UTF-8? [英] How can I make Notepad to save text in UTF-8 without the BOM?

问题描述

我有一个 CSV 文件，该文件带有特殊重音，然后通过选择将其保存在记事本中UTF-8编码.当我使用Java读取文件时，它也会读取BOM表字符.

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.

因此，我想以UTF-8格式保存此文件，而不必最初在记事本中添加BOM.

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

否则，在Java中是否有内置类可以消除读取文件内容时开头出现的BOM字符?

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?

推荐答案

1. 使用 Notepad ++ -它免费且比记事本.使用 Encoding →可以在不使用BOM的情况下保存文本. 在没有BOM的情况下以UTF-8编码:
   
   

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:
   
   

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

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

• 使用PushbackInputStream(in, 3).
• 读取前三个字节
• 如果不是BOM( EF BB BF )，请将其推回
• 将流作为UTF-8处理

• 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
