Answer 1

You have to keep two sortkey strings. One is for primary order, where German ä=a (primary a->a) and French é=e (primary sortkey e->e) and one for secondary order, where ä comes after a (translating a->azzzz in secondary key) or é comes after e (secondary key e->ezzzz). Especially in Czech some letters are variations of a letter (áéí…) whereas others stand in their full right in the list (ABCČD…GHChI…RŘSŠT…). Plus the problem to consider digraphs a single letters (primary ch->hzzzz). No trivial problem, and there should be a solution within JS.
