How to solve garbled html page

With the rapid development of the Internet, web pages have become one of the main ways for people to obtain information and communicate. The appearance of garbled characters in web pages is an unpleasant experience for both users and developers. This article will introduce common html page garbled problems and their solutions.

1. Reasons for garbled codes

1. Inconsistent encoding: The encoding of the website is inconsistent with the default encoding of the browser, resulting in garbled characters.
2. Special characters: The web page contains special characters, such as "&", "<", ">" and other characters, but they are not encoded and the browser cannot parse them correctly.
3. Font problem: The web page uses a font that does not exist or is not installed, or the browser's default font cannot correctly display the encoded characters.
4. Server setting problem: The server setting is incorrect, causing the returned data to be garbled.

2. Problem Solution

1. Check the encoding: First, you need to confirm whether the encoding method of the website is consistent with the default encoding of the browser. You can check whether the value of the charset attribute in the meta tag of the web page is correct by viewing the source code in the browser.
2. Display special characters: Special characters appearing in web pages need to be encoded. You can use html entity names, such as converting "&" to "&"; you can also use html entity numbers, such as converting "&" to "&".
3. Specify font: If the web page uses a custom font, the browser needs to correctly parse the font. You can add font description information, such as the font-face attribute, and specify the font file path and format.
4. Server settings: If the data returned by the server is garbled, you can consider modifying the server's encoding method or adding response header information, such as the charset attribute of Content-Type.

3. Common problems and solutions

1. Chinese garbled characters: Chinese garbled characters are one of the more common html page garbled characters. You can specify the correct encoding method by modifying the charset attribute in the meta tag.
2. Question mark garbled characters: When a question mark "?" appears in the browser, it means that the character cannot be displayed correctly. Typically, this is caused by the browser using the wrong encoding. You can modify the browser's default encoding or change it to UTF-8 encoding.
3. "��" garbled code: This garbled code is usually caused by the browser's inability to correctly parse special characters. You can use html entities to replace the special character or change the browser's default font to one that supports the special character.

4. Summary

The problem of garbled html pages is one of the inevitable problems in web development and needs to be solved by developers in a timely manner. By checking encoding, processing special characters, specifying fonts, and modifying server settings, you can effectively solve the problem of garbled characters. At the same time, developers should follow coding standards to ensure that the coding method of web pages is consistent with the browser's default coding, thereby improving user experience.
