      Description copied from interface: CharCollection
      Return a primitive stream over the elements, performing widening casts if needed.

      WARNING: This is not the same as converting the source to a sequence of code points. This returned instance literally performs (int)(charValue) casts. Surrogate pairs will be left as separate elements instead of combined into a single element with the code point it represents. See Character for more discussion on code points, char values, and surrogate pairs.
