Title: How to Set MySQL to Display Chinese Characters

Introduction: MySQL is one of the most popular open-source relational database management systems used for various applications. However, by default, MySQL uses the UTF-8 character encoding to display characters, which might not be suitable for Chinese users. In this article, we will guide you on how to set MySQL to display Chinese characters correctly.

1. Install MySQL with Chinese Support Before you start, ensure that you have installed MySQL with Chinese support. You can download the MySQL installer from the official website and select the Chinese language option during the installation process.

2. Configure MySQL Server to Use Chinese Characters To set MySQL to display Chinese characters, you need to configure the character set and collation settings. Here's how to do it:

Step 1: Edit the MySQL configuration file (my.cnf or my.ini) Open the MySQL configuration file using a text editor. The location of the configuration file may vary depending on your operating system. For example:

• On Windows: C:\Program Files\MySQL\MySQL Server X.X\my.ini
• On Linux: /etc/my.cnf or /etc/mysql/my.cnf

Step 2: Set the character set and collation Add the following lines to the [mysqld] section of the configuration file:

[mysqld]
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci

• character-set-server: Specifies the default character set for the MySQL server.
• collation-server: Specifies the default collation for the MySQL server.

utf8mb4 is a character set that supports the full range of Unicode characters, including Chinese characters. The utf8mb4_unicode_ci collation provides case-insensitive sorting, which is suitable for most Chinese applications.

Step 3: Restart MySQL Server After making changes to the configuration file, restart the MySQL server to apply the new settings.

3. Set the Default Character Set for MySQL Client To ensure that your MySQL client uses the correct character set, set the default character set and collation for the client. Here's how to do it:

Step 1: Open a terminal or command prompt Step 2: Run the following command:

set character-set-client-unicode=utf8mb4
set collation_connection=utf8mb4_unicode_ci

4. Test the Chinese Characters Now, create a new database and table, and insert some Chinese characters into it. Here's an example:

CREATE DATABASE test_db DEFAULT CHARACTER SET utf8mb4;
USE test_db;

CREATE TABLE test_table (
    id INT AUTO_INCREMENT PRIMARY KEY,
    chinese_column VARCHAR(255)
);

INSERT INTO test_table (chinese_column) VALUES ('你好，世界！');

You can now see that the Chinese characters are displayed correctly in the output.

Conclusion: By following the steps outlined in this article, you can set MySQL to display Chinese characters correctly. Ensure that your MySQL server and client have the necessary Chinese support, and configure the character set and collation settings appropriately.
