html opens with garbled characters

In the process of web development, we often encounter garbled characters when opening HTML. This is because HTML web pages are documents presented in the form of text. When the browser cannot correctly recognize the character encoding format, garbled characters will appear. This article will introduce the reasons and solutions for HTML opening with garbled characters.

1. Encoding issues

The most commonly used encoding format for HTML is UTF-8. When the character encoding format of the HTML file is different from the browser's default encoding, garbled characters will appear. For example, when the encoding format of the HTML file is GB2312 and it is opened in UTF-8 format in the browser, garbled characters will appear.

Solution:

1. Make sure that the encoding format of the HTML file is the same as the browser's default encoding, which is generally UTF-8 format.

2. Add the following line of code to the head of the HTML file, specifying the encoding format as UTF-8.

<meta charset="UTF-8">

When the browser requests the server, if the character encoding format of the server is different from the encoding format in the HTML file, garbled characters will also appear. This usually happens when upgrading from an old server to a new one.

Solution:

1. Keep the server encoding format consistent with the encoding format in the HTML file.

2. In the server configuration file, add the following line of code to specify the encoding format as UTF-8.

<?xml version="1.0" encoding="UTF-8"?>

3. Text editor problems

Some text editors will automatically convert the encoding format to a different format when saving the file, causing the HTML file to fail to open correctly.

Solution:

1. When saving HTML files, choose the correct encoding format. Generally, UTF-8 format is the main format.

2. Use a text editor that supports UTF-8 format, such as Sublime Text, Notepad, etc.
