/**
* Internal function used in Utf8Str copy constructors and assignment when
* copying from a UTF-16 string.
*
* As with the iprt::ministring::copyFrom() variants, this unconditionally
* sets the members to a copy of the given other strings and makes
* no assumptions about previous contents. This can therefore be used
* both in copy constructors, when member variables have no defined
* value, and in assignments after having called cleanup().
*
* This variant converts from a UTF-16 string, most probably from
* a Bstr assignment.
