What is the default character encoding of mysql database

MySQL database default character encoding

The default character encoding of MySQL database depends on the operating system and installation configuration. Generally speaking, the default character encoding is as follows:

For UNIX/Linux systems:

  • utf8mb4

For Windows:

  • MySQL 8.0 and above: utf8mb4
  • MySQL 5.7 and below: latin1

utf8mb4 is a Unicode compatible character set that supports multiple languages ​​and character sets. Latin1 is an older character set that only supports Western European languages.

Change the default character encoding

If you need to change the default character encoding, you can modify the MySQL configuration file (my.cnf) and add the following lines :

<code>[mysqld]
character-set-server=utf8mb4</code>

Next, you need to restart the MySQL service for the changes to take effect.

Impact

The default character encoding affects the character set in which data is stored and retrieved from the database. If your application and database use different character sets, this may cause data loss or display problems. Therefore, it is recommended that the application and database use the same character set to ensure data integrity and consistency.
