Hello,

  How is defined the chartset used in a COMMENT ON statement ?

    I'm getting into trouble when I execute a sql script containing
COMMENT ON statements, using isql-fb -input <script>.

    When I export the metadata ( isql-fb -x ), I see in the comments
defined by the script that characters outside ASCII range have been
replaced by two question marks ( ?? )

   The sql script is coded in UTF-8, the database has no default
charset, and Firebird version is 3.0

Thanks in advance for any clue.

Aldo
