Dear All,
I read FB 2.0 release notes that it supports UTF-8 character set,
but it did not mention UTF-16. I also read that custom character set
is possible. Does that mean I have to add UTF-16 myself if I want to
use them?

Thanks.

Adding More Character Sets to a Database

For installing additional character sets and collations into a
database, the character sets and collations should be registered in
the database's system tables (rdb$character_sets and rdb$collations).
The file misc/intl.sql, in your Firebird 2 installation, is a script
of stored procedures for registering and unregistering them.
