NodeJs - how to make function fs.writeFile write with BOM?
提问by user706355
I'm using nodeJS v0.8.6 and the native library fs. Here is my code :
我正在使用 nodeJS v0.8.6 和本机库 fs。这是我的代码：
var filesys = require('fs');
filesys.writeFile('test.txt', 'This is an example with accents : é è à ','utf8', function (err) {});
The problem is that it writes in utf8 without BOM (I use notepad++ to verify it) and it doesn't work in wordpad on Windows (the accents are not well displayed). The thing is that I need that file to be well read by womeone using wordpad.
问题是它在没有 BOM 的情况下用 utf8 写入（我使用 notepad++ 来验证它）并且它在 Windows 上的写字板中不起作用（重音显示不正确）。问题是我需要使用写字板的女性能够很好地阅读该文件。

UTF-8 doesn't require a bom, but you can add it by yourself of course.
UTF-8 不需要 bom，但您当然可以自行添加。
filesys.writeFile('test.txt', '\ufeffThis is an example with accents : é è à ','utf8', function (err) {});

I elaborated on this answer in detail on this answer - Adding UTF-8 BOM to string/Blob.
我在这个答案中详细阐述了这个答案 -将 UTF-8 BOM 添加到 string/Blob。
This is a very sparse answer that doesn't go into detail as to whythis works. The FEFF bytes are actually the UTF16LE BOM, so the previous answer is confusing.
这是一个非常稀疏的答案，没有详细说明为什么会这样。FEFF 字节实际上是 UTF16LE BOM，因此之前的答案令人困惑。
