Notepad支持Unicode編碼，使用時需選擇合適的編碼格式。要保存Unicode文件，可打開Notepad，點擊“文件＞另存為”，在“編碼”下拉菜單中選擇UTF-8（適合網(wǎng)絡(luò)和多語言字符）或Unicode（即UTF-16小端序）。若想正確查看Unicode字符，確保文件以正確編碼保存，否則可能出現(xiàn)亂碼；遇到亂碼時，可通過“文件＞打開”，手動選擇正確的編碼方式解決。日常使用中，如復(fù)制粘貼表情符號、輸入帶變音符號的字符或多語言文本，只要保存時選擇合適的編碼，Notepad均可正常顯示。但因其功能有限，復(fù)雜任務(wù)建議使用更專業(yè)的文本編輯器。

Unicode characters are a universal standard for representing text in almost all writing systems across the world. Unlike older character encodings like ASCII, which only support basic Latin letters and symbols, Unicode can handle thousands of characters from languages like Chinese, Arabic, Cyrillic, and more. This makes it essential for modern computing, especially when dealing with multilingual content.

In Notepad, the built-in text editor on Windows, Unicode support has been available for quite some time — but how you use it matters.

How to Save Files with Unicode in Notepad

Notepad gives you several encoding options when saving files, including Unicode (UTF-16) and UTF-8. Here’s how to choose:

• Open Notepad
• Go to File > Save As
• In the "Encoding" dropdown at the bottom, you’ll see:
  • ANSI – standard for older, region-specific text
  • UTF-8 – widely used on the web and supports most characters
  • Unicode – refers to UTF-16 Little Endian in Notepad
  • Unicode Big Endian – another version of UTF-16, less commonly needed

Choosing UTF-8 is usually best if you're working with text that includes special or international characters and plan to share it online or with other software.

Viewing Unicode Characters in Notepad

If you open a file containing Unicode characters, Notepad should display them correctly as long as the file is saved with the right encoding. But sometimes you might see boxes or question marks instead of characters. That usually means:

• The file wasn’t saved with the correct encoding
• The font being used doesn’t support certain characters
• The file was opened without specifying the encoding

To fix this, try reopening the file and choosing the correct encoding manually using File > Open, then selecting the right option from the "Encoding" dropdown before opening the file.

Using Unicode in Everyday Notepad Tasks

You don’t need to be a developer or linguist to benefit from Unicode in Notepad. For example:

• If you copy and paste emojis into Notepad, they’ll show up fine if the file is in UTF-8 or Unicode format.
• Writing a document with accented characters (like café or fa?ade) will preserve those accents when saved properly.
• You can even write in non-Latin scripts like Japanese or Korean and save them without losing data.

Just remember: always check the encoding when saving or opening files. Otherwise, your carefully written text might not look right later.

Notepad handles Unicode well enough for basic needs, but keep in mind it’s a simple editor. For more advanced work with multilingual text, consider using a more robust editor that clearly labels UTF-8 vs UTF-16 and offers better font control. But for quick notes or small text files with special characters? Notepad works just fine — as long as you pay attention to encoding.
