Benson Muite commented on ARROW-14290:
--------------------------------------
Some of the issues on ordering are discussed in
[https://en.wikipedia.org/wiki/Alphabetical_order#Similar_orderings]
An example sorting program for multilingual dictionaries is
[Msort|http://www.billposer.org/Software/msort.html] available under GPL3, but
the description should give some idea of flexibility that may be required.
> [C++] String comparison in between ternary kernel

> Key: ARROW-14290
> URL: https://issues.apache.org/jira/browse/ARROW-14290
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Benson Muite
> Assignee: Benson Muite
> Priority: Minor
>
> 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
