Configuring Character Encoding
Confluence and your database must be configured to use the same character encoding. To avoid problems with character encoding always set all character encodings to UTF-8 (or the equivalent for your database, for example, UTF8MB4 for MySQL databases, or AL32UTF8 for Oracle databases).
Configuring Confluence character encoding
By default, Confluence uses UTF-8 character encoding. Confluence has a number of checks in place to make sure your database is also using UTF-8 (or equivalent for your database).
While it is possible to change the character encoding, it is not recommended. Changing the Confluence character encoding will change your HTTP request and response encoding and your filesystem encoding as used by exports and Velocity templates. You may also be prevented from restarting or upgrading Confluence, depending on your database.
To change the Confluence character encoding (not recommended):
Go to and choose Edit > General Configuration
Enter the new character encoding of your choice in the text box next to Encoding then Save.
Database character encoding
Your database, and the JDBC connection to it, must be configured to use UTF-8 (or the equivalent for your database, for example, UTF8MB4 for MySQL databases, or AL32UTF8 for Oracle databases). There are a number of checks in place to warn you if your database character encoding is incorrect.
See Configuring Database Character Encoding for more information.
