Unicode is supported when the database character set is `UTF8`. In that case, Unicode characters can be used in any
|
||||
field, there is no reduction of field length for non-special fields. No special settings of JDBC driver is necessary.
|
||||
|
||||
The character set of a PostgreSQL database is determined at the time it is created. You can determine the default
|
||||
character set for a PostgreSQL cluster with the SQL command
|
||||
```SQL
|
||||
show server_encoding;
|
||||
```
|
||||
|
||||
If the default character set is not UTF 8, then you can create the database with UTF8 as its character set like this:
|
||||
```SQL
|
||||
create database keycloak with encoding 'UTF8';
|
||||
```
