    What are HTML character encodings (like UTF-8)?
    Character encodings such as UTF-8 are systems that map characters to numbers for computer storage and display. The problem is that if the browser uses incorrect encoding to parse text, it may lead to garbled code. Character encoding corresponds to a unique number for each character, for example "A" corresponds to 65. Common encodings include UTF-8, ISO-8859-1, and Windows-1252.

Use UTF-8 when saving the file; 3. Ensure that the server HTTP header specifies UTF-8. Common problems and solutions include: 1.
