打開文件後先檢查當(dāng)前編碼，通過底部狀態(tài)欄或“編碼”菜單查看；2. 若文本亂碼，嘗試在“編碼”菜單中選擇正確的編碼重新解釋，使文本正確顯示；3. 文本正常後，使用“編碼”→“轉(zhuǎn)換為”目標(biāo)編碼（如UTF-8），再保存文件，完成實際編碼轉(zhuǎn)換；4. 推薦優(yōu)先使用UTF-8編碼，必要時為兼容舊版Windows程序可選擇UTF-8-BOM，避免使用ANSI處理多語言內(nèi)容；5. 轉(zhuǎn)換前務(wù)必備份文件，若仍亂碼可嘗試其他常見編碼，批量轉(zhuǎn)換可用插件或同時打開多個文件操作。此方法無需額外工具即可解決跨系統(tǒng)字符顯示問題。

Converting encoding in Notepad is a common task when dealing with files that display strange characters (like or garbled text), especially when transferring files between different systems or languages. Here's how to do it properly.

1. Check the Current Encoding

Before converting, it's important to know what encoding your file is currently using:

• Open the file in Notepad .
• Look at the bottom-right corner of the window – it usually shows the current encoding (eg, UTF-8, ANSI, UTF-8-BOM).
• Alternatively, go to the Encoding menu at the top to see which encoding is currently selected (there will be a checkmark next to it).

Note: Just selecting an encoding doesn't change the file — it only tells Notepad how to interpret the bytes. If text looks garbled, you may need to re-interpret it using a different encoding.

2. Re-Interpret (Change Encoding Without Re-Saving)

If the text looks wrong (eg, accented characters are messed up), the file might be saved in one encoding but opened as another. You can manually tell Notepad to re-interpret it:

• Go to Encoding in the menu bar.
• Choose the correct encoding (eg, UTF-8 , UTF-8-BOM , ANSI , UTF-16 , or Encode in... > Chinese, Japanese, etc. for legacy encodings).
• The text should now display correctly.

Example: A file created in Windows (using ANSI/Windows-1252) with special quotes or é, ? might look broken when opened on another system. Switching encoding to Western European (Windows-1252) or UTF-8 may fix it.

?? This step doesn't alter the file yet — it just changes how Notepad reads it.

3. Convert and Save in a New Encoding

Once the text displays correctly, you can convert and save it in a different encoding:

• With the file open and displaying correctly, go to Encoding > Convert to [desired encoding]
  (eg, Convert to UTF-8 ).
• Then, save the file (Ctrl S or File > Save).

After conversion, the bottom-right corner will show the new encoding without "ANSI" or "UTF-8" in parentheses — it will just say UTF-8 , etc.

This actually re-encodes the file's bytes into the new format.

4. When to Use UTF-8 vs UTF-8-BOM vs ANSI

• UTF-8 : Best for web, programming, and international text. No BOM. Recommended default.
• UTF-8-BOM : Sometimes needed for Windows apps (like older Excel versions) to detect UTF-8 correctly. Adds a small header (BOM).
• ANSI : Actually Windows-1252 on Western systems. Limited to certain languages. Avoid for multilingual content.

To add BOM: Use Encoding > Convert to UTF-8-BOM and save.

Common Issues & Tips

• If converting doesn't fix garbled text, the original encoding might be misidentified. Try common ones like UTF-8 , UTF-16 , or Windows-125x encodings.
• Always backup the file before converting, especially if unsure.
• For batch conversion (multiple files), use Notepad 's “Convert” option in the “Encoding” menu while multiple files are open , or use plugins like TextFX (older versions) or external tools.

Basically, just:

1. Open file
2. Try different encodings under Encoding to make text readable
3. Then Convert to your desired encoding (eg, UTF-8)
4. Save

That's it — no extra tools needed.
