The webpage codes are exactly the same, one webpage text is garbled and the other is normal_html/css_WEB-ITnose

Like the title
This code

The text displays garbled characters
But using
the text displays normally
Write the same code in another text (copied and pasted)
Text It’s normal
, but when using

, the text is garbled


I tried many ways, and one text wrote , it can be displayed normally; another text cannot be displayed like this, but it can be changed to ... It's just dizzying. I don’t understand what’s going on! ! ! ! Asking for advice! ! ! !

This is because the encoding formats of the two html files themselves are different. Take a look at the editor's status bar. Is it that one of them shows UTF-8 and the other doesn't.

The encoding declared in the code must be consistent with the encoding format of the file itself.

The first browser screenshot is: gbk characters are output in the utf-8 page
The second browser screenshot is: utf-8 characters are output in the gbk page

The value of charset must match the actual encoding of the page file

UTF-8 is an internationally accepted encoding. Writing it in the statement can force the following text to be compiled in the code

Unified editor format ,,, and also The original poster’s code uses fewer quotation marks.

The second text can be displayed correctly without quotation marks. To be honest, some textbooks say that it can be done with or without quotation marks, but it seems that for different editors

you have to ensure:
1. When the file 99.html is stored on the disk, its encoding is "UTF-8";
2. When the browser parses the file 99.html, it uses "UTF-8" ”

To solve “1”, use window’s Notepad “Save As” to select encoding “UTF-8”, or use EditPlus for better encoding
To solve “2”, use

The second browser screenshot is: utf- is output in the gbk page 8 characters
