Description

String comparisons in C++ will use order by unicode. This may not be suitable in many language applications, for example when using characters from languages that use more than ASCII.   Sorting algorithms can often allow for the use of custom comparison functions.  It would be helpful to allow for this for the between kernel as well.  Initial work on the between kernel is being tracked in https://issues.apache.org/jira/browse/ARROW-9843
