What I do not know for sure is whether or not the file will have a BOM,
but I think Ruby can figure this out
I think that the relationships in my model are OK so far. In my concrete
case, an instance of A would be a so-called (domain-specific) user

dictionary has many entries). A C would be a so called idiom
