> 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.
