使用正確的編碼格式和輸入方法可在Notepad中正確處理特殊字符。 1. 保存文件時(shí)選擇UTF-8編碼以支持更多字符；2. 使用Alt鍵加數(shù)字鍵盤輸入特殊符號(hào)，如Alt 0169為?；3. 可從網(wǎng)頁或字符映射表複製粘貼特殊字符；4. 注意文件中的隱藏控製字符可能導(dǎo)致顯示異常。

When working with special characters in Notepad, the trick lies in understanding how encoding and input methods work together. Notepad supports a range of special characters, but you need to use the right approach depending on what exactly you're trying to display.

Use the Correct Encoding Format

Notepad defaults to ANSI or UTF-8 without BOM when saving files, which affects how special characters are displayed. To ensure compatibility:

• Save your file using UTF-8 encoding for broader character support.
• Go to File > Save As , then choose UTF-8 from the Encoding dropdown menu.

This matters especially if you're dealing with accented letters (like é, ü), symbols (like ?, μ), or characters from non-Latin scripts (like Chinese or Arabic). If you open a file and see boxes or weird symbols instead of characters, encoding mismatch is likely the culprit.

Insert Special Characters via Keyboard Shortcuts

Windows has built-in keyboard shortcuts for entering common special characters:

• Press and hold the Alt key, then type a numeric code using the number pad (not the top row).
  • Example: Alt 0169 gives you the copyright symbol ?
  • Alt 0153 inserts the trademark symbol ?

Make sure Num Lock is on before typing the numbers. This method works across many Windows applications, including Notepad.

Copy and Paste Works Fine Too

If you don't want to memorize codes or mess with encoding, just copy special characters from another source like a web page, Word document, or character map tool. Notepad handles pasted special characters well as long as the file is saved in UTF-8 format. This is the easiest way if you only need to insert a few symbols occasionally.

You can also use the Character Map app in Windows to find and copy less common characters.

Watch Out for Line Breaks and Invisible Characters

Sometimes strange symbols appear because Notepad doesn't interpret line breaks or hidden formatting correctly, especially when opening files created in other programs. You won't always see these issues, but if your text looks off or includes odd spacing, it could be due to invisible control characters not displaying properly.

In most cases, sticking with UTF-8 encoding and using copy-paste or Alt codes will cover your needs.基本上就這些.
