Yup... we would need to standardize libiconv (or an equivalent) for that
:-).

(OT: What happened to the proposal for that? Did it die from
overengineering?)

Heh. That reminds me, when will Qt classes get emplace methods? Or the
ability to accept movable-but-not-copyable types? (Or did they? Last I
checked, one or both were issues in 5.4 at least...) This is the only
reason I am (grudgingly) using STL classes for my unique_ptr's.

(Something else to consider for Qt 6 would be fixing the index types to
be size_t instead of int. Assuming we don't just drop the classes.)
