如何更改记事本（例如UTF-8，ANSI）中编码的文本？

要更改Notepad中的文本编码，可通过“另存为”菜单中的“编码”选项进行选择。具体步骤如下：1. 打开文件后点击“文件 > 另存为”；2. 在对话框底部找到“编码”下拉菜单；3. 选择所需格式如UTF-8或ANSI；4. 保存为原文件或新文件。不同编码用途各异：ANSI适用于旧系统，UTF-8适合网页和跨平台兼容，Unicode（UTF-16 LE）用于Windows应用，UTF-8无BOM则适用于某些工具偏好。检查当前编码可通过再次打开“另存为”查看下拉菜单显示。尽管Notepad功能有限，基本的编码转换已足够，如需更多功能可考虑其他工具。

When you need to change the text encoding in Notepad, like switching between UTF-8 and ANSI, it’s actually pretty straightforward. The trick is knowing where to look when saving your file.

Use the "Save As" Option to Change Encoding

The most common way to change encoding in Notepad is through the Save As menu. When you open this, you’ll see a dropdown labeled Encoding near the bottom of the dialog box. That’s where you can choose from several options like UTF-8, ANSI, Unicode (UTF-16), etc.

Here's what to do:

• Open your file in Notepad
• Click File > Save As
• Scroll down and click the Encoding dropdown
• Select your desired format (e.g., UTF-8 or ANSI)
• Make sure to save under the same name or choose a new one

This method works whether you're creating a new file or editing an existing one.

Understand What Each Encoding Means

You might wonder why there are so many encoding options. Here’s a quick breakdown:

• ANSI: This varies depending on your system language. It's older and limited compared to modern standards.
• UTF-8: A widely used encoding that supports almost all characters and symbols. Great for web pages and cross-platform compatibility.
• Unicode (UTF-16 LE): Uses more space but is often used in Windows applications.
• UTF-8 without BOM: Similar to regular UTF-8, but doesn’t include a byte order mark at the beginning, which some tools prefer.

Knowing which one to pick depends on what you're using the file for — for example, if you're writing code for the web, UTF-8 is usually best.

Check Current Encoding Before Editing

If you’re opening a file and want to know its current encoding before making changes:

• Open the file in Notepad
• Go to File > Save As again
• Look at the Encoding dropdown — it shows what the current setting is

Notepad doesn't display the encoding directly anywhere else, so this is the easiest way to check.

Keep in Mind Some Limitations

Notepad is simple, and that’s both a strength and a limitation. If you work with a lot of different encodings or need advanced features like viewing or converting multiple files at once, you might eventually outgrow Notepad. Tools like Notepad , VS Code, or even WordPad offer more flexibility. But for basic encoding changes, Notepad gets the job done.

基本上就这些。
