Answer 1

I was using 'utf8_unicode_ci' which is default by doctrine , i had to change it to :

 * @ORM\Table(name = "Table", options={"collate"="utf8_bin"})

Since some of my composite primary keys consisted of text fields. Sadly 'utf8_unicode_ci' resolved "poistný" and "poistny" as same primary key value and ended with crash at doctrine inserting flush. I could not simply change collation of one part of composite primary key, had to drop table and recreate. Hope it saves time to someone else..
