    Hello Agnieszka Kasprzyk,

    you were asking:
    > how to deal with those characters from
    > transliteration standards that do not exist as precomposed characters in
    > Unicode but they are combined of others BUT they may be combined in a
    > number of different ways. Which is the correct way?

    The ways you have outlined are "canonically equivalent", so your
    software should treat all of them as equivalent.

    > Other cases are for instance letters with two diacritics one over the
    > other.
    > What is the rule to follow in such cases?

    Multiple diacritics are placed outward from the base character,
    so you have to enter
    - either the base letter, the diacritic which is closer, the diacritic
       which is farther from the base letter, in that order,
    - or the base letter with the closer diacritic as one character,
       then the farther diacritic as the combining character.
