iconfont icon display abnormality: troubleshooting and repair

In web development, iconfont icons are widely used for their convenience and aesthetics. However, sometimes the iconfont icon will intermittently fail to display properly, even if the code is not error-free. This article will analyze a case where iconfont displays exceptions and provide a solution.

question:

Users use the following code to introduce the iconfont icon:

<code>//此处省略代码示例，因为原文没有提供具体的代码</code>

The icon displays normally most of the time, but occasionally disappears.

Analysis and Solutions:

This intermittent display exception is usually caused by CSS file encoding and parsing errors. The Unicode encoding of the iconfont icon is not parsed correctly, resulting in a display error.

During the debugging process, it was found that the Unicode value of the pseudo-element content of the iconfont font icon sometimes shows garbled code. This may be the encoding used by the browser when parsing style files is not the UTF-8 standard encoding.

Solution:

In order to avoid encoding problems, it is recommended to add @charset "UTF-8"; declaration to the style file header, and force the style file to be encoded as UTF-8. This ensures that the browser parses the CSS file with the correct encoding and correctly reads the Unicode encoding of the iconfont icon, thereby solving the abnormal icon display problem. Adding this statement can effectively prevent iconfont icon display errors caused by inconsistent encoding.
