No, here reverse logic.
I also have catch not from start.

    tertiary -- this is like in Valentina 1.x.
                aaa <> AAA
                aaa <> åaa

                upper(aaa) => AAA
                upper(åaa) => ÅAA


    SECONDARY -- ignores difference between Diacritical chars
                 i.e. Secondary difference of chars.

                aaa <> AAA
                aaa == åaa

                upper(aaa) => AAA
                upper(åaa) => AAA

    PRIMARY -- ignores difference between case of chars
                 i.e. Ignore primary difference of chars.

                aaa == AAA
                aaa == åaa

                upper(aaa) => AAA
                upper(åaa) => AAA
