    @JamesRTaylor I'm not sure how to do that within this PR. Looking at https://github.com/blog/2141-squash-your-commits,
I believe at the time you merge the PR, github should give you the option to squash all commits
into one. Will that suffice?

> Strings stored via Phoenix can be composed from a subset of the entire set of Unicode
characters. The natural sort order for strings for different languages often differs from
the order dictated by the binary representation of the characters of these strings. Java provides
the idea of a Collator which given an input string and a (language) locale can generate a
Collation Key which can then be used to compare strings in that natural order.
> Salesforce has recently open-sourced grammaticus. IBM has open-sourced ICU4J some time
ago. These technologies can be combined to provide a robust new Phoenix function that can
be used in an ORDER BY clause to sort strings according to the user's locale.
