The answer is simple for Oracle: It includes a whole zoo of locale mappings and uses each one as it is needed. This is one of the many things with Oracle that only grows over time but does never get smaller again. I suspect it's similar with MariaDB, MySQL, SQL Server and others. Only PostgreSQL has no such thing as a local inventory and relies on either glibc or ICU. Cheers, Paul
