blocks|key|1084443|text|答案是:一点也不。记事本做不到这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1084444|在java语言中，你只需跳过InputStream中的第一个字节就可以了。|1084445|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The answer is: Not at all. Notepad can't do that.

In Java you can just skip the first byte in your InputStream and be done.

blocks|key|5320406|text|请改用Notepad%2B%2B。在上面看到我的personal+blog+post。在Notepad%2B%2B中，选择“编码”菜单，然后选择“在没有物料清单的情况下以UTF8编码”。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5320407|entityMap|0|LINK|mutability|MUTABLE|url|http://blogger.ziesemer.com/2007/10/notepad.html^0|K|I|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Use Notepad++ instead. See my <a href="http://blogger.ziesemer.com/2007/10/notepad.html" rel="noreferrer">personal blog post</a> on it. From within Notepad++, choose the "Encoding" menu, then "Encode in UTF-8 without BOM".

As for a Java solution, as far as I know, Java does not understand the standard UTF-8.

<li>When I encountered this problem in Java, I didn't find any library to parse these first three bytes (BOM). So my advice:
<ul>
<li>Use <code>PushbackInputStream(in, 3)</code>.</li>
<li>Read the first three bytes</li>
<li>If it's not BOM (EF BB BF), push them back</li>
<li>Process the stream as UTF-8</li>

I just learned from <a href="https://stackoverflow.com/a/900228/2363550">this Stack&nbsp;Overflow post</a>, as @martin-geisler points out, that you can save files without the BOM in Windows Notepad, by selecting ANSI as the encoding.

I'm assuming that for more advanced uses this won't work because the resulting file is probably not the end encoding wished, but actually ANSI; but I tested and confirmed this works to save a very small .php script without BOM using only Notepad.

I learned the long, hard way that Windows' Notepad is not a true editor, although I'd like to point out for others that, despite this, it is misleadingly called up when you type "editor" on newer Windows machines, at least on one of mine.

I am currently using <a href="http://en.wikipedia.org/wiki/Emacs" rel="nofollow noreferrer">Emacs</a> and other editors to solve this problem.

Notepad on Windows&nbsp;10 version 1903 (May 2019 update) and later versions supports saving to UTF-8 without a BOM. In fact, UTF-8 is the default file format now.

<a href="https://i.stack.imgur.com/eMagy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/eMagy.png" alt="Screenshot of Notepad"></a>

Reference: <a href="https://www.bleepingcomputer.com/news/microsoft/windows-10-notepad-is-getting-better-utf-8-encoding-support/" rel="nofollow noreferrer">Windows 10 Notepad is Getting Better UTF-8 Encoding Support</a>

I have a <a href="http://en.wikipedia.org/wiki/Comma-separated_values" rel="nofollow noreferrer">CSV</a> 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?

How can I make Notepad to save text in UTF-8 without the BOM?

我有一个带有特殊重音的文件，并通过选择UTF8编码将其保存在记事本中。当我使用Java读取文件时，它也会读取BOM字符。因此，我希望将此文件保存为UTF-8格式，而不是最初在记事本中附加BOM。否则，在读取文件中的内容时，Java中是否有一个内置的类可以消除开头出现的BOM字符？
