Additional Character Sets and Collations (Language Reference Guide)
From InterBase
Go Up to InterBase Character Sets and Collation Orders
Support for additional character sets and collation orders is constantly being added to InterBase. To see if additional character sets and collations are available for a newly created database, connect to the database with isql, then use the following set of queries to generate a list of available character sets and collations:
SELECT RDB$CHARACTER_SET_NAME, RDB$CHARACTER_SET_ID
FROM RDB$CHARACTER_SETS
ORDER BY RDB$CHARACTER_SET_NAME;
SELECT RDB$COLLATION_NAME, RDB$CHARACTER_SET_ID
FROM RDB$COLLATIONS
ORDER BY RDB$COLLATION_NAME;
