Oracle Database XE is configured by default to be able to process character data in all supported languages simultaneously:

• The database is created with the Unicode AL32UTF8 character set. AL32UTF8 is the recommended database character set suitable for storing data in practically any language. Multiple languages can be mixed even in a single character value. While not a recommended option, you can modify the CHARSET parameter in the oracle-xe-18c.conf configuration file to any other valid database character set if you need to meet specific database character set requirements.

• The Oracle Database Express Edition (XE) supports the same globalization features that Oracle Database Enterprise Edition (EE) provides.
