如何使记事本保存文本在UTF-8没有BOM？ [英] How to make Notepad to save text in UTF-8 without BOM?

问题描述

我有一个具有特殊口音的 CSV 文件，并通过选择UTF-8编码将其保存在记事本中。当我使用Java读取文件时，它也读取BOM字符。

I have a CSV file with special accents and saving 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，而不是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，在读取文件中的内容时，Java中是否有任何内置类消除了开头出现的BOM字符？

Otherwise is there any 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. 使用记事本++ - 免费，比记事本好多了。在没有BOM的情况下，使用 Enconding > 在UTF-8中编码而不使用BOM ，将有助于保存文本：
   

1. Use Notepad++ - free and much better than Notepad. It will help to save text without BOM using Enconding > Encode in UTF-8 without BOM:

当我在Java中遇到这个问题，我没有找到任何库来解析这三个字节（BOM）。所以我的建议是：

When I encountered this problem in Java, I haven't found 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 $ b
• 将流处理为UTF-8

• 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
