  This method is provided for the purpose of APIs that expect only the JDK's primitive iterators, of which there are only int, long, and double.
  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.
