In Web development, it is very important to correctly set the page encoding. There is a <meta> tag in the HMTL file of each website to set the page encoding. Different encoding settings can affect the display and response of the website, so HTML specifications must be followed and the page encoding must be correctly set. This article will introduce the basic knowledge of HTML page encoding and the method of correctly setting HTML page encoding.

What is HTML page encoding?

HTML page encoding refers to the encoding method of defining characters in HTML tags. HTML files may contain various characters, such as English letters, numbers, symbols, Chinese characters, etc. In different encoding formats, the encoding value of the same character is different. If the character encoding format of the web page is inconsistent with the character encoding format displayed on the monitor, it may cause problems such as garbled codes and abnormal display.

For example, an HTML file contains two Chinese characters "Hello". For different encoding methods, the numerical codes corresponding to "Hello" are different:

    ## In the #UTF-8 encoding format, the numerical code corresponding to "Hello" is "228, 189, 160, 229, 165, 189"; in the
  • GB2312 encoding format, the numerical code corresponding to "Hello" It's "20320, 22909".
If the wrong encoding method is set in the HTML file, it will cause the website to be garbled, thus affecting the user experience.

How to correctly set the HTML page encoding?

Correctly setting the HTML page encoding can ensure the accuracy and completeness of the website text and provide users with a better user experience. Here's how to correctly set the encoding of your HTML page:

    Use the correct HTML DOCTYPE definition
HTML DOCTYPE defines the version and specification of the HTML file. There is a standard way of defining DOCTYPE in HTML5 that avoids encoding problems. In HTML5, the following code snippet is a standard DOCTYPE definition: 

<!DOCTYPE html>
This definition method can avoid version and specification issues in HTML files, and in HTML5, UTF-8 is the default encoding.

    Set the encoding format in the HTML document
At the head of the HTML document, you need to use the

<meta> tag to define the encoding format. Taking UTF-8 as an example, you can use the following code snippet to mark it: 

<meta charset="UTF-8">
    Set the encoding format in the text editor
When using the text editor to edit HTML files , you need to ensure that the character set (i.e. encoding format) of the text editor is consistent with the required character set of the HTML file. Many text editor tools can set the character set when saving HTML files, which can be selected during the saving process.

    Server-side setting encoding format
If the website uses server-side scripting, you can set the HTML page encoding through the server-side scripting language. In ASP.NET, PHP and other languages, you can use the following code to set the page encoding format: 

Response.Charset = "UTF-8"; //ASP.NET
header('Content-Type: text/html; charset=UTF-8'); //PHP
Summary

Correctly setting the HTML page encoding can avoid problems such as website garbled code and abnormal display, and at the same time improve User experience. In order to correctly set the HTML page encoding, you need to use the correct HTML DOCTYPE definition method, set the encoding format in the HTML document, and set the correct encoding format in the text editor or server side. When we follow HTML specifications and set HTML page encoding correctly, we can better provide users with a suitable website experience.
