问题
I've got a problem with inserting two rows to table. The database is in UTF8. The problem seems to be connected to the collation. This statement works:
insert into test(code,text) values('xx','aaa');
However when i try to add other row to the table:
insert into test(code,text) values('xx','aąą');
it fails with duplicate entry error. It looks like a and ą (special polish character) are threated the same. The weird thing is that when i set all collations to utf8_unicode_ci it still does not work :/ Any help will be appreciated :)

This should do the trick:
insert into test(code,text) values('xx',N'aąą');
The letter N is for Unicode insert.
