Why are trailing blanks ignored within varchars?
I think this should only apply to data types with fixed length eg. CHAR.
Is this a bug?

Tested with Firebird 1.5 RC7
Simple Testscript:
create table foo ( a varchar(10) not null );
create unique index index_a on foo (a);
insert into foo values('a' );
insert into foo values('a ');
/*or try this*/
insert into foo values(' ');
insert into foo values(' ');
