Hello, there is no problem with encoding here, but with the query that doesn’t have input parameters. Try to set query _insert into t1 (c2) values (?)_ with data flowing on the edge or execute this query by DBExecute component. ---

Yes, that’s true: only Latin letters and digits can be used in field name. Different chars could cause problems when moving graphs between computers. ---
