Configuring UTF8 Character Set for MySQL

To create a MySQL database which uses the utf8 character set:

1. Create a new database: create database <database_name> character set UTF8 collate utf8_bin

2. Open <TeamCity data directory> /config/database.properties, and add the characterEncoding property: connectionProperties.characterEncoding=UTF-8

To change the character set of an existing MySQL database to utf8:

1. Shut the TeamCity server down.

2. Being in the TeamCity bin directory, export the database using the maintainDB tool: maintainDB backup -D -F database_backup (more details about backup are Creating Backup via maintainDB command-line tool)

3. Create a new database with utf8 as the default character set, as described above.

4. Modify the <TeamCity data directory> /config/database.properties file --- change connectionUrl property to:

5. jdbc:mysql://<host>/<new_database_name>

6. Import data the new database: maintainDB restore -D -F database_backup -T <TeamCity data directory>/config/database.properties

7. Start the TeamCity server up
