Collation defines how strings are compared and is used when creating a COLLATE expression.
The COLLATE expression can be used in the WHERE clause when comparing two strings or in the
ORDER BY clause when specifying how the order of the query results. CouchbaseLite provides
two types of the Collation, ASCII and Unicode. Without specifying the COLLATE expression
Couchbase Lite will use the ASCII with case sensitive collation by default.
Creates a Unicode collation that will compare two strings by using Unicode Collation
Algorithm. If the locale is not specified, the collation is Unicode-aware but
not localized; for example, accented Roman letters sort right after the base letter
