How to solve garbled Chinese characters in html5

HTML5 is a new generation of standardized language that allows developers to more easily develop powerful and beautiful websites. However, in the process of using HTML5 for website development, many developers will encounter a very common problem - Chinese garbled characters.

Chinese garbled characters may appear in various parts of the website, such as garbled characters when entering text in the input box, garbled characters when displaying data on the web page, etc. These problems have brought a lot of inconvenience to users and also affected the aesthetics and user experience of the website. So, why do Chinese garbled characters appear?

First of all, what you need to understand is: computers can only process numbers. Therefore, inside the computer, all characters are converted into numbers. In the encoding system ASCII (American Standard Code for Information Interchange), only English letters, numbers and some commonly used symbols are included. This results in that Chinese cannot be displayed under ASCII encoding. With the development of computer technology, in order to meet the needs of more languages, people have invented more encoding systems, such as GB2312, GBK, Big5, etc.

Among these encoding systems, GB2312 is one of the earliest encoding schemes used for Chinese characters. It contains most of the Chinese characters and symbols. With the advancement of computer technology, GB2312 can no longer meet the needs of modern Chinese, so GBK encoding was introduced, which supports more Chinese characters. In Taiwan, people use Big5 encoding. In HTML5, we use UTF-8 encoding, which is a cross-language encoding scheme that is compatible with countless languages.

However, even if UTF-8 encoding is used, the problem of Chinese garbled characters still exists. At this time, you need to check whether there is a problem in the HTML5 code. The main reason for Chinese garbled characters is that the HTML5 encoding does not match the character set on the web page. In HTML5, we need to set the character set of the web page through the meta tag, for example:

<meta>

Here, the charset attribute specifies the character set of the web page to utf-8. If our web page contains other languages, then we need to set the character set accordingly, for example:

<meta>

Here, iso-8859-1 is the character set encoding of Western Europe. It should be noted that the character set setting must be consistent with the encoding scheme, otherwise the problem of Chinese garbled characters will occur.

In addition, there are some other reasons that can also cause Chinese garbled characters, such as the browser does not support UTF-8 encoding, or the encoding method is inconsistent when using the database, etc. We also need to solve these problems accordingly.

In short, Chinese garbled characters are a very common problem in HTML5 development, but by properly setting the character set and using the correct encoding method, we can easily avoid this problem. Hope this article is helpful to everyone!
