Why?
Unicode! `char` is UTF-8, which means a character can be from 1
to 4 bytes. val.front gives a `dchar` (UTF-32), consuming those
bytes and giving you a sensible value.
But the value fits into a char; a dchar is a waste of space. Why
on Earth would a different type be given for the front value than
the type of the elements themselves?
