utf8mb4 is a character set in MySQL that extends utf8, supporting more character encodings, especially emoji and some less common characters.<\/p>\n

The main functions of utf8mb4 are as follows:<\/p>\n

    \n
  1. Support for more characters: utf8mb4 can store any Unicode character, including emoji expressions and some special symbols, while utf8 can only store some Unicode characters.<\/li>\n
  2. Solving the storage length limit issue: utf8mb4 can store more characters, resolving the problem of utf8 potentially exceeding storage length when storing certain characters.<\/li>\n
  3. Compatibility with other systems: Some applications or systems use the utf8mb4 character set. If the database does not support utf8mb4, it may result in garbled characters or display issues.<\/li>\n
  4. Support for multiple languages: utf8mb4 is more suitable for storing text in multiple languages, including Chinese, Japanese, Korean, etc.<\/li>\n
  5. Support for more sorting rules: utf8mb4 supports a wider range of sorting rules, allowing for more accurate sorting and comparisons.<\/li>\n<\/ol>\n

    In conclusion, the utf8mb4 character set in MySQL expands the functionality of the utf8 character set by supporting a wider range of character encodings, including emoji and less common characters, providing improved support for multilingual data storage.<\/p>\n","protected":false},"excerpt":{"rendered":"
